Apulley of radius r and moment of inertia i = 2 mr2 is mounted on an axle with negligible friction. block a with a mass m and block b with a mass 3m are attached to a light sting that passes over the pulley. assuming that the string doesn’t slip on the pulley, answer the following questions in terms of m, r, and fundamental constants a. what is the acceleration of the two blocks? b. what is the tension force in the left section of the string? c. what is the tension force in the right section of the string? d. what is the angular acceleration of the pulley?

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.
