Transcribed Image Text:3. Consider a load of mass 120.0 kg that is being held up by two tensioned cables. Cable
1, with tension T1, is strung at 60° to the horizontal. Cable 2, with tension T2, is strung at
25° to the horizontal.The load is at rest.
(a) Draw and label a free body diagram for the load
(b) Find both forces of tension
(c) The cables each have a cross sectional area of 9x105 m², and are made of a material
with ultimate tensile strength of 85.0 MPa. What is the safety factor for each cable?
