A 25 kgf weight P is held in equilibrium by two strings which run over two pulleys Counterbalances Q and R are attached to free ends of the strings One of the counterbalances weighs 20 kgf the sine of the angle formed by the string and the vertical is 0 6 Neglecting friction of the pulleys determine the weight R of the other counterbalance and the angle a formed by the second string with the vertical The weight of the strings may be neglected A 20 kg 53 B 20 kg 37 P B C 15 kg 37 D 15 kg 53
