Non-coplanar non-concurrent forces are those forces which
Which is the correct statement about law of polygon of forces?
Concurrent forces are those forces whose lines of action
A 5 kg sphere is accelerated upward by a string whose breaking strength is 200 N. The maximum value of acceleration with which the sphere can move without breaking the string is (take acceleration due to gravity. g = 10 m/s2)
The set of forces, whose resultant is zero, are known as-
The forces whose line of action lie along the same line are known as:
In collinear force system the forces whose line of action lie on:
The forces, whose lines of action lie in the same plane and are meeting at one point, are known as
The point, through which the whole weight of the body acts, irrespective of its position, is called
Limiting force of friction is defined as the frictional force which exists when a body
A force is completely defined when we specify:
When a body is subjected to two forces, the body will be in equilibrium if the two forces are:
When a body resting on an inclined surface just begins to slide down the inclined plane under the action of its own weight, then the angle of inclination of the inclined plane is
An attempt is made to pull a roller of weight W over a curb (step) by applying a horizontal force F as shown in the figure. The coefficient of static friction between the roller and the ground (including the edge of the step) is μ. Identify the correct free body diagram (FBD) of the roller when the roller is just about to climb over the step.
The principle of conservation of angular momentum for a rigid body is applicable when:
