A and B that only exert vertical reactions on the shaft. J l
Determine its smallest diameter d if the allowable bending
stress is (:3l
A solution for problem 5 using Mohrs circle will be provided in lecture of office hours if requested. Email
Dave with any questions regarding this problem.
Now solving 9-16 with Mohrs circle:
Note: The bar rotates about point A, therefore the arc length formula may be used to determine vertical
displacements at all points upon the bar.
Note: Problem 4.41 will be discussed Wednesday 6/24 in
Note: For this problem no shear stress is applied to the element. For this reason when transforming
into Mohrs circle the applied stresses sigma x and sigma y are the principle stresses. However, when

and is supported by smooth bearings at D and E. It is
coupled to a motor at F, which delivers 12 kW of power to
the shaft while it is turning at
