Each of the cables can sustain a maximum tension of 5000 lb. The uniform beam has a weight of 4200 lb . a) Determine the shortest time possible to lift the beam with a speed of 10 ft/s starting from rest. t = ?

A tugboat with a displacement of 50 tonnes and resistance of 750 kN is towing a 75-tonne bargewith resistance of 1000 kN. The tugboat has a propeller generates thrust of T to move it forward,while the barge is non-propelled. Determine the thrust and the force exerted by the rope on thetugboat, given that it takes 35 seconds for the tugboat to uniformly increase its speed to 13.5knots.

Use work and energy to calculate the final angular velocity (e) of the 10kg bar. The bar has the initial motion shown and displaces 0 = 90°. 2m 3 radis

Give the solution.
