A compound shaft consists of brass segment (1) and aluminum segment (2). Segment (1) is a solid brass shaft with an allowable shear stress of 69 MPa. Segment (2) is a solid aluminum shaft with an allowable shear stress of 86 MPa. If a torque of TC = 23900 N-m is applied at C, determine the minimum required diameter of the brass shaft d1 and the aluminum shaft d2.

A) The minimum required diameter of the brass shaft D₁ = 0.00176 m

B) The minimum required diameter of the aluminium shaft D₂ = 0.00142 m

Step-by-step explanation:

Data:

A compound shaft has two segments made of brass and aluminium

Allowable shear stress of Brass = 69 MPa.

allowable sheer stress of Aluminium = 86 MPa.

Torque TC = 23900 N-m

Find: Minimum required diameter of the brass D₁ and Auminium D₂

Solution: see attached picture for workings that shows the break down of the minimum diameter for each segment of the shaft.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
