Problem Set 3: Problem 1. Problem: A hammer thrower is swinging a hammer whose head A has mass M . The head rotates at constant speed, v , in a horizontal circle of radius ρ . The angle of wire BC relative to the horizontal plane is θ as shown. (a) Solve for the tension in wire BC, T , and the speed v . Express your answers in terms of M , ρ , θ and gravitational acceleration, g . (b) Compute T and v for M = 7 kg, ρ = 1 m and θ = 33 o . Solution: The following figure shows the forces acting on the hammer head. Specifically, in the vertical direction, we have the weight of the head,

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
