1. THE CORRECTED VERSION FOR THE HANGING MASS PROBLEM

2. Consider this example
300 T1
600 T2
Both T1 and T2 have horizontal and vertical components
1.2N

3. Here it is the Tensions T1 and T2 that have to be resolved

4. Here it is the Tension T1 and T2 that have to be resolved
T1cos 600
T1cos 300
300 T2
600
And T1 cos300 and T2 cos600 are vertical components of T1and T2
And
They add together to produce the force which is equal and opposite the load

5. The calculation below gives the vertical component of the tension in each wires. In our example this is equal to 1.2N
T1cos300 +T2cos600 T1 T2

6. The Horizontal Components of T1 and T2
300 T2
600

7. The Horizontal Components of T1 and T2
T1sin300
T1sin600 T1
300 T2
600
Because the load is stationary the horizontal components of force must be equal

8. 1. So For the vertical components of the tension we have
2. For the horizontal components we have
From 2
Substituting for T1 in 1 gives us T2 = 0.6N and T1 = 1.04N
