The angle at which the teeth are inclined to the normal of the axis of rotation is called _______________

The angle at which the teeth are inclined to the normal of the axis of rotation is called _______________ Correct Answer lead angle

Lead angle is the angle at which the teeth are inclined to the normal of the axis of rotation. Lead angle of the worm gear is same as the helix angle of the helical gear. Thus, Ψ2 = λ1.

A rigid body is rotating about an axis. One force F1 acts on the body such that its vector passes through the axis of rotation. Another force F2 acts on it such that it is perpendicular to the axis of rotation and at a point 5cm from the axis. This force F2 is perpendicular to the radius vector at its point of application. Find the net torque on the body. Let F1 = 10N & F2= 5N.
