Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Draw the cam profile for a knife-edge follower having the followingmotion: rise 50 mm during 150 deg turn with gravitational motion, dwell for 30deg, fall 50 mm during 150 deg turn with gravitational motion, and dwell for 30deg. Use 100 mm base circle. Cam rotates clockwise. Scale 1:1
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
A cam have the following specifications: Follower to move outward through 5 cm during 90° of cam rotation, it dwells for the next 60°. The follower then return to its original position through an angle 0R and then dwell for the rest of the cam rotation of 110°. The displacement of the follower is to take place with constant speed motion during both the outward and return strokes. The least radius of the cam is 4 cm. If the cam rotates at 300 r.p.m., construct the displacement, velocity and acceleration diagrams. Also determine The displacement, velocity, acceleration and the pressure angle for the following angles (40°, 75°, 145°, 200°).

The drum of a winch system is rotating at 294 RPM and the drum has a diameter of 8 inches. What is the linear speed at the surface of the drum in feet/sec? This is the same speed at which the cable of the winch is pulled in.
Identify which variables are the outputs or how they relate to the outputs. Plug in all possible numbers. Assuming link 2 rotates at a constant rate of 80 rpm CW, determine the velocity of link 6 when link 2 makes a 10-degree angle with the ground (measured as a right hand horizontal)
