Engineering Mechanics - Section 1 (2)

When a rigid body is suspended vertically, and it oscillates with a small amplitude under the action of the force of gravity, the body is known as

A resultant force is a single force which produces the same effect as produced by all the given forces acting on a body.

Mass moment of inertia of a uni form thin rod of mass M and length (l) about its mid-point and perpendicular to its length is

A redundant frame is also called __________ frame.

The equivalent length of a simple pendulum which gives the same frequency as compound pendulum is

The path of the projectile is a parabola.

The angle between two forces when the resultant is maximum and minimum respectively are

The triangle law of forces states that if two forces acting simultaneously on a particle, be represented in magnitude and direction by the two sides of a triangle taken in order, then their resultant may be represented in magnitude and direction by the third side of a triangle, taken in opposite order.
