You have to tell us the angles from vertical or horizontal or what.
if from horizontal
T1 cos 45 = T2 cos 30
.707 T1 = .866 T2
T2 = .816 T1, so T1 is the one that will break
m g = T1 sin 45 + T2 cos 30
m g = .866 T1 + .866 (.816) T1
m g = .866 T1 + .707 T1 = 1.57 T1
m g = 1.57 * 1700 = 2674 N
m = 2674/9.81 = 273 Kg
The two angled ropes used to support the crate in (Figure 1) can withstand a maximum tension of 1700N before they break. What is the largest mass the ropes can support?
The two angles given are 30 degrees and 45 degrees.
