The apparatus consists of a shaft supported by ball bearings upon which three different

types of cams can be mounted.The push rod for follower is supported vertically, which can

adopt three different types of followers.. A variable speed motor rotates the cam. A dial

gauge permits plotting of follower displacement with respect to cam position. By operating

the system at different Speeds, jump speed can be found and also the effect of weight and

spring force on jump speed can be studied.

SPECIFICATIONS:

1.  Cam -Eccentric, tangent and circular ARC type - one each.

2.  Follower- mushroom, flat faced and roller type - one each.

3.  Cams and followers are hardened to reduce wear of the surfaces.

4.  Variable speed motor coupled to camshaft of suitable range and Variac.

5.  A dial gauge to note the follower displacement.
