**[SOLVED] Finding Tensions IS SO FUN**

## Homework Statement

Find tesnions T1, T2, and T3 and M in figure attached...

## Homework Equations

## The Attempt at a Solution

To start i drew three FBD

A) for mass on left

Fm= T2-m*g = 0

B)the intersection

Fx = T3 cos 37 - T2 cos 63 = 0

Fy = T2 sin 63 + T3 sin 37 - T1 = 0

C) mass of box

F = T1 - mg

so...

C) box

T1 = (6.00kg)*(9.80m/s^2) = 58.8 N

B) Intersection

.799T3 - .454T2 = 0

.891T2 +.602T3 = 58.8N

.891T2 + .602[((.454/)(.799))*(T2))] = 58.8

1.23T2= 58.8N

T2= 58.8/1.23= 47.8N

T3 = ((.454/)(.799))*(T2); = ((.454/)(.799))*(47.8); T3 = 26.8

A) T2/g = m (47.8N)/(9.80 m/s^2) = m = 4.87kg
