The force applied and the diameter of the diameter of a hardened steel ball is kept constant while four different specimen blocks namely, aluminum, brass, copper and mild steel are penetrated by the indentation steel ball to create different indentations on each of them. The diameters of the indentions allow us to obtain the Brinell Hardness number to predict the hardest and the softest material among them. The experimental data would also allow us to compare the hardness measured with the other published results from other…
My team’s second prototype balsa wood tower performed significantly better than our first tower. The first tower held 27.5 lbs. while the second held 90 lbs. The main differences in the towers come from the increased thickness of load-bearing wood. We made the four corner pieces three sticks thick instead of only one stick. We also decreased the amount of cross pieces to make sure we were under weight. The both towers ended up crushing because the weight was unevenly distributed on the bottom. On the first tower, the cross pieces were opposite on either side, but on the second tower, the cross pieces mirrored on either side. Even though the second tower’s weight bearing strength was higher, it buckled under.…
It is getting too dangerous for players today to be using metal bats. The most dangerous position for players is pitcher because they are the closest to the batter at sixty feet six inches away from home plate. Balls hit up the middle of the field off metal bats give pitchers an average reaction time of 0.056 seconds less than that of balls hit with wood bats. This could be a difference of life and death (Shively 1). This is very little time to get out of the way of a ball. In my recent experience, we were playing Tennessee Westland and our lead-off man Chris Rankhorn hit a line drive back up the middle hitting the pitcher in…
Baseball has been around since 1846 and wooden bats have always been the tool of the trade. There is much debate as to whether players should use wooden bats versus aluminum. Traditional wooden bats can make players feel connected to the historical game. As well, there are a few benefits to using wooden bats opposed to aluminum. Here’s a list of 5 baseball wood bat benefits:…
My research revealed three main points to me. One being that metal bats have a larger “sweet spot” than wood bats. The “sweet spot” of a baseball bat is a place on the bat where the ball leaves the bat with the greatest speed and the player's hands feel very little vibration from the impact. This is because a metal bat’s barrel can hold a uniform shape longer than a wood bat. This larger “sweet spot” provides a better chance for the ball to not only be hit but hit harder.…
I remember the first time I bought a pool cue. I had just started playing pool and was getting used to the warped house cues that would sometimes send the balls scrambling in undetermined directions. That is why I decided to buy my own cue and did this without knowing that there is actually a bit of basic knowledge needed to select the right one. Well, I figured that out real quick. First of all, I didn't realize that I would need to spend over $15.00 for a good cue. To get a good cue, you need to be prepared to pay over $100 and use that money to buy a wooden one. Wood does not react to temperature as bad as other kinds and does not bend so easily (although house cues would almost disprove this, but they are abused daily). I can say that…
If you will be playing baseball, paintball, or other activities that require eye protection from projectiles, balls, bats, or rackets, high index lens materials lack the impact resistance of polycarbonate. Eye protection in these activities also requires a large lens that protects the eyes from impacts coming from any direction. In addition,…
Generally, all bats have a similar shape and wing structure though different species have finer details depending on the diet and social adaptations. Bat species vary in size. The largest bats may weigh up to 2.2 pounds and have a wingspan of up to five feet. The smallest mature bats have a mere wingspan of six inches and weighs about 0.07 pounds. Bats have mouths closely resembling that of rats…
When beginning to learn how to throw and catch, this praised saying controlled the thoughts when thinking of a glove as the main protection shield from injury. Without having a face mask cover the player's entire face, there is no excuse for not seeing the ball since there is no plastic or metal bars blocking the directional path of the fast-moving yellow sphere. There is a common stigma that the player’s who wear the masks are afraid of the ball, stripping them of their identity as the tough, intimidating player they want to be known for. This also contributes to the myth that college coaches do not consider recruiting players with masks because of the common misconception, a mask means the athlete is scared of the ball. This is not always true, as college coaches recruit because of talent, and several other factors when thinking about a successful team. As long as the player is comfortable either way, the coach will always be looking out for the player’s well being no matter if the pitcher wears a mask or…
Local changes in North Carolina towns and neighborhoods can be made in effort to promote bat life. Installing bat boxes around local homes can positively impact bats in local areas by providing an area for roosting (Bat House General Information). The best location for bat houses are on top of poles or buildings which provides the best protection from predators (Bat House General Information). Once a resident the bat will begin to feed on insects, therefor lowering the local insect population. Adding bat houses to a local community can benefit both parties, bat and human populations.…
As was previously stated our main competitor in this industry is Play Air’s “Inflatable Ben Wallace Defender.” This product not only has many flaws but it also has the target market of only youth players, whereas our Shot Blocker targets a wide array of consumers. It is also a much more practical product, it is sturdier, bigger, moving, and solves…
The baseball bat was broken when it was bought by the plaintiff. The plaintiff should return the baseball bat and have his money refunded to him. When the plaintiff bought the baseball bat from the defendant the baseball bat was already broken because as soon as the defendant used the bat to play baseball, the bat shattered into a million pieces. Shattering into a million pieces certainly violates the implied warranty of merchantability under the Uniform Commercial Code (UCC 2-314). No Industria De Calcados Martini Ltda. v. Maxwell Shoe Co., 36 Mass. App. Ct. 268 (Mass. App. Ct. 1994) INDUSTRIA DE CALCADOS MARTINI LTDA. v. MAXWELL SHOE CO., INC. No. 92-P-1322 APPEALS COURT OF MASSACHUSETTS 36 Mass. App. Ct. 268; 630 N.E.2d 299; 1994 Mass. App. LEXIS 274; 23 U.C.C. Rep. Serv. 2d (Callaghan) 89 December 20, 1993, Argued March 21, 1994, Decided. Also, there’s a case what case ? that expounded upon this issue and told us that a baseball bat can’t crack when it’s for its intended purpose. Otherwise, the store has to refund the to the plaintiff. Dudzik v. Klein's All Sports, 158 Misc. 2d 72 (N.Y. J. Ct. 1993) Laurence Dudzik et al., Plaintiffs, v. Klein's All Sports, Defendant. SC# 92-390 JUSTICE COURT OF NEW YORK, TOWN OF COLONIE, ALBANY COUNTY 158 Misc. 2d 72; 600 N.Y.S.2d 1013; 1993 N.Y Misc. LEXIS 272; 21 U.C.C. Rep. Serv. 2d (Callaghan) 592 June 9, 1993, Decided. The information that can be clearly drawn from these cases is if a plaintiff buys a baseball bat, the said bat must be in the condition that the was represented by the seller. The bat must be in marketable condition so that the implied warranty from the seller to the buyer must be…
AIR BAG MANUFACTURING PROCESS Muhammad Junaid Ali 11-14-11 Group :: 5 Background • An air bag is an inflatable cushion designed to protect automobile occupants from serious injury in the case of a collision • Air bag is designed to supplement the protection offered by seat belts which are needed to hold occupant securely in place especially in side impacts, rear impacts, and rollovers. • Upon detecting a collision, air bags inflate instantly to cushion the exposed occupant with a big gasfilled pillow • An air bag consists of an air bag module (containing an inflator or gas generator and an air bag), crash sensors, a diagnostic monitoring unit, a steering wheel connecting coil, and an indicator lamp. Raw materials • An air bag module has three main parts: the air bag, the inflator, and the propellant. The air bag is sewn from a woven nylon fabric and can come in different shapes and sizes depending on specific vehicle requirements.…
