Question

Two blocks, each of mass m 5 3.50 kg, are hung from the ceiling of an elevator as in Figure P5.31. (a) If the elevator moves with an upward acceler ation aS of magnitude 1.60 m/s2, find the tensions T1 and T2 in the upper and lower strings. (b) If the strings can withstand a maximum tension of 85.0 N, what maximum acceleration can the elevator have before a string breaks?

Answer 1

string breaks at acceleration of 1.58m/s62
