What is the main function of a cam in mechanical systems?
A
Convert rotary motion into linear motion B
Store energy C
Reduce friction D
Measure torque
Analysis & Theory
Cams convert rotary motion into linear or reciprocating motion.
Which of the following is a **type of cam**?
A
Radial cam B
Helical cam C
Spiral cam D
Pulley cam
Analysis & Theory
A radial (disc) cam is commonly used in valve mechanisms.
What is the component that moves due to the cam’s shape?
A
Slider B
Gear C
Follower D
Spring
Analysis & Theory
The follower is the element that responds to the cam's motion.
Which follower type has **rolling contact** with the cam?
A
Knife-edge follower B
Roller follower C
Flat-faced follower D
Oscillating follower
Analysis & Theory
Roller followers reduce friction by rolling instead of sliding.
Which cam type uses a **groove on a cylinder** to guide a follower?
A
Radial cam B
Wedge cam C
Cylindrical cam D
Flat cam
Analysis & Theory
Cylindrical cams use grooves to guide the follower along a cylinder.
Where are cams commonly used?
A
Electric circuits B
Engines for valve timing C
Water pumps D
Bearings
Analysis & Theory
Cams are widely used in IC engines for operating valves.
Which part supports the cam and follower in a cam mechanism?
A
Frame B
Belt C
Crank D
Housing
Analysis & Theory
The frame supports the cam and the follower system.
In a wedge cam, motion is created by:
A
Rotation B
Translation (sliding) C
Oscillation D
Groove-following
Analysis & Theory
Wedge cams move in a straight (translating) path.
