ENGINEERING MECHANICS

Is the turning effect produced by a force, on the body, on which it acts

All of these

Is equal to the product of force acting on the body and the perpendicular distance of a point and the line of action of the force

Is equal to twice the area of the triangle, whose base is the line representing the force and whose vertex is the point, about which the moment is taken

Potential energy

None of these

Kinetic energy

Power

All of these

Bears a constant ratio to the normal reaction between the two surfaces

Is independent of the area of contact, between the two surfaces

Always acts in a direction, opposite to that in which the body tends to move
