Question:

Two blocks each of mass m = 3.50 kg are fastened to the top of an elevator as in figure.

(a) If the elevator has an upward acceleration a = 1.60 {eq}m/s^2 {/eq}, find the tensions {eq}T_1 {/eq} and {eq}T_2 {/eq} 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 the upper string breaks?

Newton's Second Law:

As per Newton's second law, the net force acting on the body in any direction is equal to the multiplication of mass of the matter of the body and the acceleration of the body in that particular direction.

Given Data:

  • The mass of the each block is: {eq}m = 3.5\;{\rm{kg}} {/eq}.
  • The acceleration of the elevator is: {eq}a = 1.6\;{{\rm{m}}...
