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 1.5kN/m and the spring is unstretched when Î¸ = 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) Î¸ = 20o,

(b) Î¸ = 30o .

a = 0.5 m wwww
