Two blocks are connected by a massless string which passes over a massless, frictionless pully. The block of mass mA=10kg rests on a surface inclined at theta = 37 degree to the horizontal. The block of mass mB hangs freely. The coefficient of static friction between mA and the surface is 0.40. The blocks are at rest.
where m1 = mA and m2 = mB
A) Draw the free body diagram of the blocks.
B) What is the maximum value of mB for which the blocks remain at rest?
