Duestions 4-1 relate to the system Show! Velow. ROPE 2 CONTINUOUS OVER THE DRUM BUT DOES NOT GO COMPLETELY AROUNO THE DRUM KLOCKA 225 ROPE 2 ROPE 1 BLOCKE 45 kg 150 mm DIAMETER 150 mm 300 mm 90 kg CONTAINER 250 mm BLOOKC 50 kg CYLINDRICAL DRUM FRICTIONLESS PN BRAKE LEVER BRAKE PAD 25 m 50 mm mg TO 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 Blocks B and C=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) equals 90 kg. What is the maxi- mum turning moment the brake is capable of resisting? (A) 66 N (B) 132 N (C) 265 N (a) 440 N ace (A) 17.6 Nem (B) 106 Nm (C) 212 Nom (D) 1,484 Nem 10. When Block A is at rest with respect to Block C, what is the value of the friction force between Block A and Block B? (A) ON (B) 45 N (C) 110N 2.220 N
