Theory of Machines MCQ with Answers

301) For simple harmonic motion of the of follower, a cosine curve represents

Answer is:

acceleration diagram

302) In S.H.M., the velocity vector w.r.t. displacement vector

Answer is:

leads by 90°

303) A body having moment of inertia o:m2 is rotating at 210 RPM and r with another body at rest having I40 kg m2. The resultant speed after ing will be

Answer is:

90 RPM

304) Inertia force acts

Answer is:

opposite to the direction of accelerating force

Explanation:

A force equal in magnitude but opposite in direction and collinear with the applied force or impressed force producing the acceleration, is known as inertia force.

Mathematically, inertia force, F=-m.a
