- The rope connecting the two blocks of Fig. passes over a fixed drum. The coefficient of friction be- tween the left block and the floor is 0.50; between the right block and the floor, 0.40; and between the rope and the drum, 0.30. Determine the minimum and maximum mass of the left block for which motion does not occur. 15 m 2 m 1.5 m 100 kg 40 30arrow_forwardBlock A has a mass of 29 kg and block B has a mass of 41 kg. The two blocks are stacked on the ramp with an incline of 0 = 32.2°. Determine the largest horizontal force F that can be applied to block B without either block moving for each of the following two cases: a.) The friction coefficient for the contact between blocks A and B is Hs1 = 0.6 and the friction coefficient for the contact between block A and the ramp is Hs2 = 0.22. b.) The friction coefficient for the contact between blocks A and B is µs1 = 0.6 and the friction coefficient for the contact between block A and the ramp is Hs2 = 0.55. F A Part a) The limiting slip condition occurs at the contact between A and the ramp v The maximum force before either block A or B slips is N Part b) The limiting slip condition occurs at the contact between A and B The maximum force before either block A or B slips is >arrow_forwardDetermine the minimun force that is needed for F to move B to the right.
