Two massless and frictionless pulleys are used to drag a large mass (m = 645 kg) up an inclined slope (0 = 18.0°) with light rigid cables. The larger pulley remains fixed in position with the help of a strong cable (under tension T) connected to a rigid wall. The coefficient of static friction between the mass and the slope is µ = 0.270. A force F is applied vertically downwards to pull the mass up the slope. T T₂ T₁ 0 m T3 F

Question
Please help me with this
- Draw a free-body diagram of all the forces acing on the mass m and for all the forces acting on both the pulleys.
- Show that the minimum tension T1 for the mass to start sliding up the slope is about 3580 N.
- Hence, determine the tensions T2, T3 and the minimum force F for the mass to start sliding up the slope.
- Assuming that the cables with tensions T2 and T3 remain parallel to the inclined slope, determine the magnitude of the tension T in the strong cable just as the mass starts sliding up the slope.
