A block of mass 60.0 kg is suspended at rest by two cables shown below. The top is ceiling, and the left side is wall.

Question

a) Calculate the tension force T1

b) Calculate the tension force T2

Answer 1

vectors T1+T2+W = 0

x-component T1cos45 - T2cos25 +0 =0

y-component T1sin45 - T2sin25 -mg =0

From the x-component equation, get T1 in terms of T2.

Substitute in the y-component.

Viola!
