Acceleration‚ Velocity and Displacement On A Downward Ramp 3/3/2014 Purpose: To determine the velocity and acceleration of an object at different positions going down a ramp at four different angles. Hypothesis: If an object is accelerating at different angles then the larger angles will always have the largest acceleration. Materials: Ramp Miniature car Ticker Machine Masking tape Ticker tape Carbon paper Power supply Ruler Procedure: 1. A ramp was angled at 3

Except for the points on the axis‚ all the points on a rotating rigid object during any time interval move through the same angle. Many equations describing circular motion require angles to be measured in radians (rad) instead of degrees. Any angle θ measured in radians‚ in general‚ is defined by the equation. If the arc length‚ s‚ and the length of the radius‚ r‚ is equal‚ the angle θ swept by r is equal to one radian. The units cancel and the abbreviation radian is substituted because θ is the ratio

Teaching trigonometry using Empirical Modelling 0303417 Abstract The trigonometric functions sin(x)‚ cos(x) and tan(x) are relationships that exist between the angles and length of sides in a right-angled triangle. In Empirical Modelling terms‚ the angles in a triangle and the length of the sides are observables‚ and the functions that connect them are the definitions. These well-defined geometric relationships can be useful when teaching GCSE-level students about the functions‚ as they

Q1 - Define engineering drawing. Why drawing is called universal language of engineers? Ans1:-A drawing drawn by an engineer having engineering knowledge for the drawing purposes is an engineering drawing. It is meant for communicating his ideas‚ thoughts and designs to others. Engineering drawing is a starting point of all engineering branches such as Mechanical‚ Production‚ Civil‚ Electrical‚ Electronics‚ Computer science‚ Chemical etc. It is spoken‚ read‚ and written in its own way.

They are also used for work holding and inspection on the shop floor. In some shop work holding applications‚ the accuracy would not need to be to the level of lab or inspection gage blocks. V-blocks are precisely square‚ and the V-groove should be in the exact center of the block. The prime purpose of a V-block is to

gear that has been around the longest. Spur gears have teeth that run perpendicular to the face of the gear. | | Helical Gears | Helical gears are very similar to spur gears except the teeth are not perpendicular to the face. The teeth are at an angle to the face giving helical gears more tooth contact in the same area. Helical gears can also be used on non-parallel shafts to transmit motion. Helical gears tend to run quieter and smoother than spur gears due to the increased number of teeth in
