5. The shaft of a motor has a length of 15 times its diameter and has a maximum twist of 1.5 degrees when twisted at 2.5 KN-m torque. If the modulus of rigidity of the shaft is 83 Gpa, find the shaft diameter in mm.

A solid cantilevered aluminum alloy rod, 10-mm in diameter, supports a Parol (Christmas Lantern). The hanging Parol subjects the rod to a bending moment of 10.2 Nm along the x-axis, as well as Torque (T) at its fixed end (Section B). If the yield strength oYield in tension of the aluminum alloy is 103.9 MPa at point n of Section B, what is the maximum torque the rod can carry under the maximum distortion-energy theory (MDET)?

Solve it correctly please l will rate accordingly.

Calculate the reaction forces on the bearing near the pulley and bearing at the far end of the shaft. Include a free body diagram and coordinates. Given the shaft length is 1 meter=  Mass=40Kg  Static load = 8600N Dynamic (running load) = 8400N   Some hints:1. This solution will require you to draw known forces and find unknown reactions in 2perpendicular planes and then add the horizontal and vertical reaction forces asvectors to find the reaction force (hypotenuse).2. Bearings are usually mounted as near as possible to the ends of the shaft withoutfouling the other machine elements. The bearing at the far shaft end can be mountedat the 1 meter point. The bearing at the pulley end should allow clearance to assemblethe pulley.3. Bearing reaction forces are typically simplified as a single point load through thebearing centre.

A borehole drilling machine with a vertical shaft of 60 mm diameter is 500 mm long and is supported in long bearings at its top end. The shaft has Youngs modulus of E = 110 GN/m2.  A disc of mass 40 kg is attached to the center of the shaft. The center of the disc is 0.25 mm from the geometric axis of the shaft. Neglecting any increase in stiffness due to the attachment of the disc to the shaft, calculate: 1.1. The critical speed of rotation.  1.2. The maximum bending stress when the shaft is rotating at 80% of the criticals peed.

Handwritten solution+FBD and explanation.

The shaft in the diagram below is subjected to bending forces of 8kN at B and 5 kN at C as shown in the diagram. The shaft is supported in bearings near its ends at A and D. Calculate the maximum bending moment in the shaft. Give your answer to 2 d.p. in Nm but do not include units in your answer. e.g. 5000.00 NOT 5000N m

Can someone help me to my activity to understand this. Thank you!! :))

A stepped shaft ABC consisting of two solid, circular segments is subjected to torques T}and T2acting in opposite directions, as shown in the figure. The larger segment of the shaft has a diameter of dv- 2.25 in. and a length Lt= 30 in.; the smaller segment has a diameter d2— 1.75 in. and a length L, = 20 in. The torques are T, = 21,000 lb-in. and fz=10.000 lb-in. (a) Find reaction torque TAat support A. (b) Find the internal torque T(x) at two locations: x = L1/2 and x = L1+ L2/2. Show these internal torques on properly drawn free-body diagrams (FBDs).
