A force of 20 N is applied at the small plunger. a) What is the pressure produced in the cylinders? (40000 N/M2) b) What is the thrust exerted on the large plunger? (400 N) c) How much work is done by the operator‚ if the smaller plunger moves down 0.1 m? (2J) 4.

VARIOUS LAB TEST ON CEMENT: Checking of materials is an essential part of civil engineering as the life of structure is dependent on the quality of material used. Following are the tests to be conducted to judge the quality of cement. 1. Fineness 2. Soundness 3. Consistency 4. Initial and Final Setting Time of Cement FINENESS OF CEMENT: We need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement

The process and criteria needed for our experiment is the same as that of any other scientific experiment. We will prepare the research experiment based on our hypothesis that ToughMet 3 TS 95 Alloy Engineered Sucker Rod Couplings will last longer than traditional sucker rod couplings. Our team will then work to accept or reject this hypothesis. Our experiments will have the ability to be duplicated so the conclusions we come up with whether it fails to reject or rejects the original hypothesis will

The Metal Casting or just Casting process may be divided into two groups: Hot Forming Process Examples are Centrifugal casting‚ Extrusion‚ Forging‚ Full mold casting‚ Investment casting‚ Permanent or Gravity Die casting‚ Plaster mold casting‚ Sand Casting‚ Shell Mold casting. The method to be used depends upon the nature of the products to be cast. Cold Forming Process Examples are Squeeze casting‚ Pressure die casting‚ Gravity die casting‚ Burnishing‚ Coining‚ Cold forging‚ Hubbing‚ Impact

this is complete‚ an instrument known as the "introducer" is inserted into the vagina. The instrument is much like a long syringe with a plunger going through the center. The vet then will push his hand through the anus and guide the introducer along the cervix. The instrument is pushed through the cervix and into the uterus. Once it reaches the uterus‚ the plunger is pulled out and a catheter is inserted into the uterus‚ against the uterine horn‚ through the center of the introducer. The "cuff‚" a

Introduction: Temperature - Is a measure of the motion of particles‚ increasing the temperature will cause the particles to move faster because the reactant particles have more thermal energy from the heat. When particles move faster‚ more frequent collisions will occur and the collisions are more violent. This should increase the reaction rate. This will result in the particles colliding more frequently and increasing the speed of the reaction. Also when they have more energy there will be more

Grade 9 Task Term 3 Hydraulics and Pneumatics Section: A 1. a) Good examples of hydraulic systems include automotive brakes‚ and the control systems of large aircraft. Hydraulic systems supply forces somewhere remote from where it is practical to locate large machinery. Hydraulics gives high forces with low losses‚ thanks to the virtual incompressibility of hydraulic fluids. Pneumatics is usually less efficient‚ though simpler since the "reservoir" in the circuit is the atmosphere

What Factors Affect the Rate of Photosynthesis in living leaves? Abstract: In this lab‚ four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light‚ capture light‚ and use light as energy for reproduction and growth‚ by photosynthesis. The control in this experiment was spinach‚ which was tested before any of the other plants were. The other plants that were tested were English Ivy‚ C4 Plant‚ and a multicolored

punch‚ 10 spinach leaf disks were cut out for each cup. Each set of leaves were placed into two separate syringes. The plunger was replaced into the syringes and pushed in until only a small volume and air and leaf disked remained in the barrel (without damaging the leaf disks). Then‚ a small volume of the sodium bicarbonate plus soap water was pulled into the syringe. The plunger was then pulled even farther back‚ with one finger on the opening of the syringe‚ creating a vacuum. It was held for about
