If the speed of the shaft is doubled in given Problem, what will be the percentage increase in the heat transferred from the bearing? Assume that the bearing remains at constant temperature.
ProblemAn automobile crankshaft is 3.175 cm in diameter. A bearing on the shaft is 3.183 cm in diameter and 2.8 cm long. The bearing is lubricated with SAE 30 oil at a temperature of 365 K.
Assuming that the shaft is centrally located in the bearing, determine how much heat must be removed to maintain the bearing at constant temperature. The shaft is rotating at 1700 rpm, and the viscosity of the oil is 0.01 Pa s.
A force of F= (-2i+8j-6k)N is applied to an object that is constrained to move in the direction u=0.5571i+0.4481j-0.6992k. If the object has a total displacement of 10 meters in the direction of u, calculate the work done on the object by the force.
Is there a difference in the family demographics of people who stay at motels? Suppose a study is conducted in which three categories of motels are used: economy motels, modestly priced chain motels, and exclusive motels.
