plz help me solve quick Q.2. (8 Marks) The 50-mm-diameter shafts AB & DE are made of A-36 steel (G - 75 GPa) and are supported on journal bearings that allow the shafts to rotate freely and the turbine at E is fixed from turning. If the allowable angle of twist of C with respect to E is 0.2° and shaft AB rotates at 30 Hz, determine the maximum power (hp) that can be delivered from the motor Motor 1.5...
Alt h. 10- The motor delivers 40 hp to the 304 stainless steel shaft while it rotates at 20 Hz. The shaft is supported on smooth bearings at A and B, which allow free rotation of the shaft. The gears C and D fixed to the shaft remove 25 hp and 15 hp, respectively. Determine the diameter of the shaft to the nearest 1/8 in. if the allowable shear stress is 8 ksi and the allowable angle of twist of...
Problem 1 (25 Points) Two solid steel (6-80 GPa) shafts are connected by the gears shown. Shaft (1) has a diameter of 45 mm, and shaft (2) has an outside diameter of 55 mm and wall thickness 4 mm. Assume that the bearings shown allow free rotation of the shafts. If a 400 N-m torque is applied at gear D, determine (a) the maximum shear stress magnitudes in each shaft. (b) the angles of twist ф, and ф (c) the...
The two shafts are made of A-36 steel. Each has a diameter of 23 mm and they are connected using the gears fixed to their ends. Their other ends are attached to fixed supports at A and B. They are also supported by journal bearings at C and D, which allow free rotation of the shafts along their axes. A torque of 500 N·m is applied to the gear at E as shown in the figure below. The shear modulus...

Figure Q3 (a) shows a solid 40 mm diameter steel shaft which is supported by smooth bearings at B and D. It is coupled to a motor at C, which delivers 6 kW of power to the shaft while it is turning at 50 Hz. The modulus of rigidity of steel is 80 GPa. The shaft is free to turn in its support bearings at B and D. If gears A and E consume powers of 2 kW and 4...
75 mm 1.5 m T = 48 N·m 2 m 150 mm Two solid steel 20-mm-diameter shafts are coupled together using the perfectly meshed gears shown. Shaft DC is fixed to the wall at D and supported with a frictionless journal bearing. Shaft EF is supported with two frictionless journal bearings. The modulus of rigidity of steel is 80 GPa. Before the torque is applied, the angle of twist in each shaft is zero, and the angle of rotation of...
Backboard O dynamic balancing QUESTION 27 Q20: The rotor of a steam turbine with mass 10.5 kg is mounted on steel shaft (E 207 GPa). The shaft diameter is 49 mm and is 1.8 m long. The shaft is supported at the two ends by the bearings. The turbine rotor has an eccentricity of 9.0 mm and operates at 7200 rpm (754.0 rad/s). Determine the natural frequency of the system in rad/s.

A temporary support steel frame (E 200 GPa) is made of 30-mm diameter solid circular steel rods (members AB and CD), and 22-mm diameter solid circular steel rods (members BC and AD), al pin connected at the turnbuckle corners A, B, C, and D (see Figure below). The steel frame is braced by two cables AC and BD. A turnbuckle is fitted to cable AC and tightening it will induce tension 3m in cable AC. Determine the largest allowable tension...
