The shaft is supported at its ends by two bearings a and b and is subjected to the forces applied to the pulleys fixed to the shaft. the 400-n forces act in the z- direction and the 200-n and 80-n forces at in the positive y direction. the journal bearings at a and b exert only y and z components of force on the shaft. determine the normal force at d in the x-direction

1. study the scenario. the particles in some system are moving around quickly. a few minutes later, the particles are moving, on average, more slowly. how does this change in motion affect the temperature of the system? the temperature of the system did not change. the speed of the particles does not affect temperature, the number of particles affects the temperature.the temperature of the system is lower now than it was initially. faster moving particles result in a higher temperature for the system.the temperature of the system is higher now than it was initially. slower moving particles result in a higher temperature for the system.the temperature of the system did not change. the speed of the particles has no effect on the temperature, only the type of atom affects the temperature.
