Test: Velocity & Acceleration Analysis - 2 - Question 4

A crank of radius 15 cm is rotating at 50 rpm with an angular acceleration of 60 rad/sec2. The tangential acceleration of the crank is about

Detailed Solution for Test: Velocity & Acceleration Analysis - 2 - Question 4

at = αr = 60 x 0.15 - 9 m/s

Test: Velocity & Acceleration Analysis - 2 - Question 5

Two points A and B located along the radius of wheel as shown below, have velocities of 80 and 140 m/s respectively.​

Test: Velocity & Acceleration Analysis - 2 - Question 7

Klein’s construction can be used when

Detailed Solution for Test: Velocity & Acceleration Analysis - 2 - Question 7

Klein’s construction is used to determine the acceleration of various parts and this method is used when crank has uniform angular velocity.

Test: Velocity & Acceleration Analysis - 2 - Question 8

Coriolis component of acceleration is always

Detailed Solution for Test: Velocity & Acceleration Analysis - 2 - Question 8

Coriolis component of acceleration appears in the direction perpendicular to the link.

Test: Velocity & Acceleration Analysis - 2 - Question 9

A constrained kinematic chain (mechanism) has n number of links. What is the number of instantaneous centres

Test: Velocity & Acceleration Analysis - 2 - Question 10

There are two points P and Q on a planar rigid body. The relative velocity between the two points

Detailed Solution for Test: Velocity & Acceleration Analysis - 2 - Question 10

Given any two points A and B on a rigid body, let line AB be passing through points A and B, then the components of velocity of A and B along the line AB are always equal as the distance between A and B never changes or we can say relative velocity along AB is always zero.

Hence the relative velocity of the points must be perpendicular to the line joining them.
