Find the magnitude of the torque produced by a 4.5 N force applied to a door at a perpendicular distance of 0.26 m from the hinge. Answer in units of N · m.

The required torque is 1.17 N-m.

Explanation:

The given data : -

The magnitude of force (F) = 4.5 N.

The length of arm (r) = 0.26 m.

Here given that force is applied at perpendicular means (∅) = 90°.

The torque (T) is given by

T = F * r * sin∅

T = 4.5 * 0.26 * sin 90°

T = 4.5 * 0.26 * 1

T = 1.17 N-m.
