If tension in the cable supporting a lift moving downwards is half the tension when it is moving upwards, the acceleration of the lift is
Non-coplanar non-concurrent forces are those forces which
Which is the correct statement about law of polygon of forces?
Which of the following do not have identical dimensions?
Concurrent forces are those forces whose lines of action
A person who weighs 800 N steps onto a scale that is on the floor of an elevator car. If the elevator accelerates upward at a rate of 5 m/s2, what will the scale read?
Centroid of circle lies at:
Centre of mass of a body
A bullet a mass m kg is fired horizontally with a velocity v m/s from a pistol of mass M kg. The recoil velocity of the pistol is
If a system is in equilibrium and the position of the system depends upon many independent variables, the principle of virtual work states that the partial derivatives of its total potential energy with respect to each of the independent variable must be
Who founded the principle of virtual displacement?
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:
