A solid shaft made from copper is 90mm diameter and 8m long
A solid shaft made from copper is 90mm diameter and 8m long. If this shaft is joined to a 1.5m long solid steel shaft and 120mm diameter, estimate the maximum shear stress in each material and the total angle of twist of the entire shaft, if a torque of 20KN-m is applied to each end of shaft. GC=40GN/m2 G=90GN/m2
Physics: Uniform Motion
A motorboat maintained a
constant speed of 15 miles per hour relative to the water in
going 10 miles upstream and then returning. The total time
for the trip was 1.5 hours. Use this information to find the
speed of the current.
Ans: 5 mi/hr.
Any solution for this? Thanks
