The shaft shown in Figure 2 is subjected to loads at pulleys attached on each end, as shown. It is supported by bearings that allow free rotation of the shaft. 

The loads on the pulleys are 377 and  888.

a) Determine the normal stress at section , a distance 0.22 from the first pulley, at position A on the cross-section.

(tensile stress is positive, report to 3 significant figures)

c)  Determine the normal stress on the bottom surface of beam ABC at the section , a distance 0.5 from the support at A.

(positive value for tensile stress, report to 3 significant figures)

c)  Determine the maximum shear stress on the neutral axis of beam ABC at the section , a distance 0.5 from the support at A.

(positive value for shear stress when arrows meet at top right corner of stress element, report to 3 significant figures)

c)  Determine the normal stress on the top surface of beam ABC at the section , a distance 0.5 from the support at A.

(positive value for tensile stress, report to 3 significant figures)

 ii) The shear force, V, is

(downward shear force on the right surface is positive, report to 3 significant figures)

 iii) The bending moment, M, is

(clockwise rotation on right surface is positive, report to 3 significant figures)

 b)  Determine the internal forces acting at the section , a distance 0.5 from the support at A along the beam ABC.

i) The normal force, N, is

(positive value for tensile force, report to 3 significant figures)

An engine hoist is used to lift an engine that weighs 380 kg, as shown in Figure 1. The beam ABC is made of steel square tubing outer dimensions 100 x 100 mm with wall thickness 6 mm. Assume 

a)    Determine the axial load in the hydraulic cylinder BD.

Please choose the correct range for your surname from the options below to receive your experimental readings.

Note the setup name (i.e. SETUP 1) on your practical worksheet.

I hereby confirm that I have watched the video, from beginning to end, demonstrating how a 3 element 45° rectangular strain gauge rosette is used to measure the strain on the outer surface of an air reservoir while pressurizing the reservoir to two different pressures. I confirm that I will complete the worksheet on my own and submit answers based on my own calculations.  I understand that copying or using someone else's work constitutes cheating. This is a formal assessment and any form of cheating will result in disciplinary action.

You may discuss the general approach with fellow students, but ultimately the final version of your submission must be your own individual work.
