Question:

A collar B of weight W is attached to the spring AB and can move along the rod shown. The constant of the spring is 1.5 kN/m and the spring is unstretched when en θ = 0. Knowing that the coefficient of static friction between the collar and the rod is 0.40, determine the range of values of W for which equilibrium is maintained when

(a) θ = 20^o,

(b) θ = 30^o.

a =0.5 m www
