Q2. (80%) A plate cam must provide the displacement shown in Figure below to a reciprocating in-line roller follower. The roller diameter is 1.0 in. The cam must have a base circle of 3.0 in. and rotate clockwise. Graphically construct the profile.

Draw the displacement diagram and profile of the cam operating a roller reciprocating follower and with the following data: Shaft diameter 10 mm; Minimum radius of cam 25mm; lift = 40mm; roller diameter=15mm. The cam lifts the follower for 120° with Simple Harmonic Motion (SHM) followed by a Dwell of 30° .Then follower lowers down during 150° of cam rotation with SHM followed by a Dwell period. If the cam rotates at a uniform speed of 100 RPM clockwise direction. Calculate the maximum velocity and acceleration during the ascent and descent period. Maximum Velocity and Acceleration During Ascent and Descent

3. 100-gram oil at 20°C and 50-gram iron at 75 °C are placed in 200-gram iron container. The increase in temperature of the container is 5°C and the specific heat of oil is 0.43 cal/g °C. What is the specific heat of the iron?

The maximum sliding velocity of the teeth of two gear wheels in mesh is 0.32 m/s. The wheels are of module 5 mm and have 32 and 44 teeth respectively. The addendum for each wheel is 1.2 times the module and the pressure angle is 20°. Calculate: 2.1. The number of teeth in contact. 2.2. The angular speed of each wheel.
