Bar AC is straight arid has 106 in. length, B is a pulley that supports forces W and F, W is vertical, and the t direction is parallel to bar AC.

(a)    If  F = 150 lb and α = 30°, determine the coordinates of point C so that the t component of the resultant of F and W is zero.

(b)   If  F = 150 lb and C is located at (56, 90) in., determine angle α so that the t component of the resultant of F and W is zero.

(c)    If C is located at (56,90) in. and α = 30°, determine F so that the t component of the resultant of F and W is zero.

Hint: For each of these questions, first find the x and y components of the resultant force and then use the transformation given in Prob. 2.35 to obtain the t component.
