13. A Pulley shown in the illustration has a radius of 2.7 m and a moment of inertia of 39.0 kg m^2. The hanging mass is 4.20 kg and it exerts a force tangent to the edge of the pulley. Another mass, 5.80 kg, hangs from the other end of the cord providing a counter torque. (A) What is the angular acceleration of the pulley? (B) What is the acceleration of the hanging mass? What is the tension is each cord? I = 1/2 M R^2

14. A treasure chest, length = 30 cm, width = 20 cm and height = 10 cm, is filled with gold, density = 19,300 kg/m^3. (A) What is the mass of this gold? If it is submerged in a liquid of density = 1030 kg /m^3

(B) What would be the buoyant force on the chest?

Find the moment of inertia of a circular disk of radius R and mass M that rotates on an axis passing through its center. [Answer: ½ MR2] Step 1: Pictorial representation: Sketch a neat picture to represent the situation. Step 2: Physical representation: 1) Cut the disk into many small rings as it has the circular symmetry. 2) Set up your coordinate system and choose its origin at the pivot point (or the axle location) for convenience. Then choose a...

A sphere of mass M, radius r, and moment of inertial I = Mr2 (where is a dimensionless constant which depends on how the mass is distributed in the sphere) is placed on a track at a height h above the lowest point on the track. The sphere is released, and rolls without slipping. It reaches a horizontal surface which subsequently bends into a vertical loop-the-loop of radius R, as in Fig. 2 below. a) When it reaches the top...
