When a force of 10.0 N is exerted on the handle of a door, the door can be just opened. If the handle is a distance of 50 cm from the hinges find the torque applied on the door.

When the temperature of a coin is raised by 75^@C , the coin's diameter increase by 2.3xx10^(-5)m . If the original diameter of the coin is 1.8 xx10^(-2) m, find the coefficient of linear expansion .

The handle of a door is at a distance 40cm from axis of rotation. If a force 5N is applied on the handle in a direction 30^@ with plane of door, then the torque is

The handle of a door is at a distance 40 cm from axis of rotation. If a force 5Nis applied on the handle in a direction 30^(@) with plane of door, then the torque is
