Question 1

The Cam and follower are used to function in a reciprocating machine. They are connected to frame to form a kinematic pair. The Cam & Follower will form a :

• ASingle-link mechanism
• BTwo-link mechanism
• CThree-link mechanism
• DFour-link mechanism

Question 2

The below given fig. shows a cam mechanism, imparting some motion to the follower. Thus the type of follower is;

• AReciprocating follower
• BRotating follower
• COscillating follower
• DCannot be determined

Question 3

Which of the following mechanism is similar to that of an eccentric of a steam engine ?

• ARack & Pinion
• BCam Mechanism
• CChain drives
• DNone of these

Question 4

The follower starts from rest at beginning and it comes to rest at end of stroke. During its travel the follower may follow approximately with of the following motion :

• AUniform velocity
• BSHM
• CCycloidal
• DAll of these

Question 5

The angular displacement of the cam during outstroke is θ_o. If the time required for the return stroke is 1.5 sec then the time required for the follower during the outstroke will be given by.

• AS/r
• Bθ_o/ω
• Cθ_R/ω
• Dnone of these

Question 6

In the mechanism given below, if the angular velocity of the eccentric circular disc is 1 rad/s, the angular velocity (rad/s) of the follower link for the instant shown in the figure is
