Two window washers, Bob and Joe, are on a 3.00-m-long, 335-N scaffold supported by two cables attached to its ends. Bob weighs 755 N and stands 1.00 m from the left end,Two meters from the left end is the 500-N washing equipment. Joe is 0.500 m from the right end and weighs 850 N. Given that the scaffold is in rotational and translational equilibrium, what are the forces on each cable?

Question

Two window washers, Bob and Joe, are on a 3.00-m-long, 335-N scaffold supported by two cables attached to its ends. Bob weighs 755 N and stands 1.00 m from the left end,Two meters from the left end is the 500-N washing equipment. Joe is 0.500 m from the right end and weighs 850 N. Given that the scaffold is in rotational and translational equilibrium, what are the forces on each cable?
a. left cable _________ kN
b. right cable _________kN

I will be happy to check your work. Also, do remember sum of vertical forces is zero.

Fy=0= T1+t2-755-335-500-850 Sum of tor. =0= (T2*3)-755(1)-335(2)-500(2)-850(2.5) I solved for T1=923.34 and T2=1516.666 But it's still wrong. I'm not sure what I am doing wrong
