It is easier to open a door by pushing at a point away from the hinge than at the point close to the hinge.

Why is it easier to open a door by applying the force at the free end of it.

The angle of elevation of top of a tower from a point on the ground is 30^@ and it is 60^@ when it is viewed from a point located 40 m away from the initial point towards the tower the height of the tower is

(A) : It is harder to open and shut the door if we apply force near the hinge. (R ) : Torque due to a given force is maximum at hinge of the door.

Use absolute value concept to find the distance between : a. two points 'S' and 'T' such that, point 'S' is 9 m away from the origin towards right and point 'T' is 2 m away from the origin in the opposite direction. b. the points : 26 and -17.

Why is it easier to push a heavy block from behind than to press it on the top and push?

It is easier to pull a lawn roller than to push it because pulling

A set of points is such that each point is three times as far away from the y-axis as it is from the point (4,0).Then locus of the points is:

A set of points is such that each point is three times as far away from the y-axis as it is from the point (4,0).Then locus of the points is:

A : It is very difficult to open or close a door if force is applied near the hinge. R : The moment of applied force is minimum near the hinge.

When a body is hinged at a point and a force is acting on the body in such a way that the line of action of force is at some distance from the hinged point, the body will start rotating about the hinged point. The angular acceleration of the body can be calculated by finding the torque of that force about the hinged point. A disc of mass m and radius R is hinged at point A at its bottom and is free to rotate in the vertical plane. A force of magnitude F is acting on the ring at top most point. Component of reaction at the hinge in the vertical direction is
