15 Points Einstein is holding a 5.0 kg dumbbell in each hand (Figure 1) . He is set rotating about a vertical axis, making one revolution in 2.0 s. His moment of inertia (without the dumbbells) is 3.0 kg-m2 when his arms are outstretched, and drops to 2.4 kg-m2 when his arms are pulled in close to his chest. The dumbbells are 1.0 m from the axis initially and 0.20 m from it at the end Determine the Moment of Inertia of Einstein with the Dumbbells when his arms are outstretched and when they are pulled close to his chest Determine the angular velocity of Einstein Before and After Determine the Kinetic Energy Before and After (Is energy conserved?  Explain)

15 Points A uniform horizontal beam of mass M = 6.3 kg and length 6 m is attached to a wall by a hinge. Its far end is supported by a cable that makes an angle of θ = 30° with the beam and it provides a tension T. A box of mass m= 2.1 kg also hangs from the beam. The box of mass m is a distance of 5 m to the right of the hinge. What is the tension T in the cable? What is Nx, the horizontal component of the force the hinge (or pivot) exerts on the beam? What is Ny, the vertical component of the force the hinge (or pivot) exerts on the beam?

According to the DSM-5, two specific symptoms must be present everyday for at least two weeks and at least four of seven other symptoms to meet the criteria for Major Depressive Disorder (MDD). The two specific symptoms that must be present in all cases to meet the criteria for MDD are:

15 Points Determine the distance s to which the 57 kg painter can climb without causing the 3.3 meter ladder to slip at its lower end A.  The top of the 24 kg ladder has a small roller (no friction between the wall and the ladder), and at the ground, the coefficient of static friction is 0.29.  The center of mass of the painter is directly above her feet.
