Find the tensions T1 and T2 in terms of m, a, and g.
Which string would break first if a was sufficient large?
What are the tensions if the cable supporting the elevator breaks?
Homework Equations
F = ma
The Attempt at a Solution
My answers were:
T1 = 2(ma + mg)
T2 = ma + mg
the upper string would break first
T1 = 2(-ma + mg)
T2 = -ma + mg
can anyone please check my work and see if these answers are correct? thanks
