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.

Q5:- A symmetrical cam with circular flank operates a flat-footed follower. The lift is 8 mm, base circle radius is 25 mm and the nose circle radius is 12 mm. If the total angle of cam action is 120°, find the maximum acceleration when the cam shaft rotates at 500 rpm.
In a cylindrical type of cam in which the follower reciprocates or -------- in a direction parallel to the cam axis
A cam is used to operate a platform that repeatedly lifts boxes for a height of 40 mm as shown. One cycle of the cam has the following motion requirements: Rise to 40 mm in 1.5 s, Dwell for 0.25 s, Fall for 20 mm in 1 s; Dwell for 0.25 s; Fall a further 20 mm in 1s and the cycle repeats after this. The required speed of cam is rpm and the angle turned by cam during the Rise motion is degrees. *Write your answer only as numbers, DO NOT add any text 40 mm
