QUESTION
18 m and mass 3.48 kg.
A weight of 42 N is attached to the free endof a light string wrapped around a pulley ofradius 0.18 m and mass 3.48 kg. The pulley (auniform disk) is free to rotate without frictionin a vertical plane about the horizontal axispassing through its center. The weight isreleased 5.14 m above the floor.Determine the tension in the string. Theacceleration of gravity is 9.8 m/s2.Answer in units of N
Solution: Weight of the object,Mass of the object,Mass of the pulley,Radius of the pulley,For the counter weight, let be the tension in the sting and Applying Newton’s second law, Considering...
