The shaft is supported at ils ends by two bearings a and band is subjected to the forces applied to lhe pulleys fixed to the shaft. determine the resultant internal loadings acting on the cross section at point c. the 400-n forces act in the - z dir ection and the 200-n and 80-n forces act in the y direction. the journal bearings at a and b exert only y and z components of force on the shaf1.

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
