1. The rotating solid steel shaft is simply supported by bearings at points B and C and is driven by a gear (not shown) which meshes with the spur gear at D, which has a 150-mm pitch diameter. The force F from the driver gear acts at a pressure angle of 20 degree. The shaft transmits a torque to point A of TA =340 N.m. The shaft is machined from steel with S,-420 MPa, Km2.5, S=134MPA and N=2. Draw shear and bending diagrams and calculate diameter of shaft. 250 mm 100 mm

Illustrate and completely solve the problem! Write legibly or type written the solutions. The shaft assembly is made from a steel tube 1 in. in diameter, which is bonded to a solid brass core 0.5 in. in diameter. If a torque of 250 lb-ft is applied at its end, determine the maximum shear stress in psi experienced by the assembly. Take G for steel at 11.4 x 103 ksi and G brass at 5.2 x 103 ksi.

The motor A delivers 3000 hp to the shaft at 1500 rev/min, of which 1000 hp is removed by gear B and 2000 hp is removed by gear C. 1.) Determine the maximum shear stress in the shaft in ksi. (Answer in 2 decimal places) 2.) Determine the angle of twist in degrees of end D relative to end A. Use G = 12 x 106 psi for steel, and assume that friction at bearing D is negligible. (Answer in 3 decimal places)
The two solid shafts are connected by the gears shown. The motor constantly supplies 20 kW of power at 15 Hz to system at A. The yield shear stress is 140 MPa for shaft (1) and 220 MPa for the shaft (2), and over all factor of safety is 2. a) Find the diameter of both shafts. b) If the modulus of rigidity of shaft (2) G is 77.2 GPa, calculate the relative angle of twist D with respect to C. 30 teeth B (1) 48 teeth Tp 0.8 m

Design a hallow shaft (Diameter and length) that develops 80 kW of power while rotating at a speed of 4000 rpm. The design constrains are as under:The angle of twist not to exceed 0.200Shear stress is not to exceed 480 MN/m2The outer diameter is to be twice the inner diameter. The shaft length is to be three times the outer diameter. Modulus of rigidity = 79 GN/m2.
NEED DETAILED ANSWER ASAP, THANK YOU The four rigid gears, loaded as shown in the figure, are attached to a 2.89-in.-diameter steel shaft.
