Page 3 of 3 5. Two blocks are arranged as shown and acted on by
forces P and Q. Block A weighs 300 N and block B
weighs 200 N. The coefficient of static friction between
all surfaces is S = 0.3, and the coefficient of kinetic
friction between all surfaces is K = 0.2.
(a) (7 marks) If force Q = 0, determine the value of P if
motion is impendin...
