Question

Two blocks each of mass m-2.94 kg are fastened to the top of an elevator as in the figure below T, (a) Ir the elevator has an upward acceleration a-1.60 m/s,find the tensions 7i and Ta in the upper and lower strings 3352 X Ti- Your response differs from the correct ar wer by more than 10%. Double check your calculations. N T-6703 Your response differs from the correct answer by more than 100%. N (b) If the strings can withstand a maximum tension of 92.0 N, what maximum acceleration can the elevator have before the u 5.83 s pper string breaks? Need Help? ose es

Explanation / Answer

T1 = 2m ( 9.81 + 1.6) = 2*2.94*11.41 = 67.09 N

Tension in string 1 is 67.09 N because it hangs 2 masses.

T2 = 2.94*11.41 = 33.54 N

string 2 hangs only one mass.
