Castill relate to the system shown below NORTE ROPES BER NO NOOR DET 300 CONTANEN 25 BOX 10 CALORCA 7777 TO PN BREVE PO ho 201 Coefficients of friction are as follows: Between the 90-kg cylinder and the supporting surface - 0.50 Between Blocks A and B -0.50 Between Block Band -0.50 Between Block C and the supporting surface 0.20 Between the brake pad and the drum=0.80 Between the drum and Rope 20.30 Assume the ropes are massless 9. What is the minimum tension in Rope 1 between the 90-kg cylinder and Block B that will cause the cylinder to move? IL Assume that the brake is fully on and the mass (m) quals 90 kg. What is the maxi mum tuming moment the brake is capable of resisting (A) (A) 66 N (B) 132 N (C) 265 N (D) 440 N 176 Na (B) 106 Nm (C) 212 NE (D) 1,484 NO 10. When Block A is at rest with respect 10 Block C, what is the value of the friction force between Block A and Block B? (A) ON (B) 45 N (C) 110 N (D) 220 N
