As shown below, a 15 kg bar that is 3.2 m long is set up to rotate about its center (the yellow circle). Force B is acting 77 cm from the left end of the bar. Express each answer using appropriate mks units. A = 20 N B = 21 N C = 22 N $$\theta_A = 77^\circ$$ $$\theta_B = 79^\circ$$ Determine each individual torque, the net torque, and the direction the bar will rotate. $$\tau_A = 9.89 N(m)$$ $$\tau_B =$$ $$\tau_C = 35.2 N(m)$$ $$\tau_{net} = 24.68 N(m)$$ Direction of rotation = Counterclockwise

A spherical vessel of 50-cm radius contains a liquefied gas at -187\deg C. It has two jackets oflagging each 10-cm thick. The thermal conductivities of the inner and outer layers are inthe ratio of 2:3. The temperature of the outermost surface is 15\deg C. If the heat leakage rateinto the liquid gas is 225 W, find the thermal conductivities of the lagging material
