The gear is made from SAE 8650 OQT 1000 steel The width of the hub of the gear mounted at this location is 45 mm. Design the key. The standard key dimension for a 50-mm-diameter shaft would be 14mm '9 mm Q-1 a rectangular. Material...
QUESTION 1 It is required to design a square key for fixing a gear on a shaft of 27 mm diameter. The shaft is transmitting torque of 195,844 N.mm to the gear. The width of the key is equal 7 mm. The key is made of steel 50C4 (sy - 577 N/mm2) and the factor of safety is 3. For key material, the yield strength in compression can be assumed to be equal to the yield strength in tension. Determine...
QUESTION 1 The cross section of a key for a 41 mm diameter shaft. The Torque transmitted by shaft to hub is 636,348 N-mm. The key is made of steel having Syt - 380 MPa and the factor of safety is 2. Determine the length of the key (mm) in Shear.
P1.022 The handle shown in the figure is attached to a 50-mm-diameter shaft with a square shear key. The forces applied to the lever are P-1,200 N. If the average shear stress in the key must not exceed 125 MPa, determine the minimum dimension a that must be used if the key is 35 mm long. The overall length of the handle is = 0.70 m. ta - Shear Key Handle Shaft Answer: a
Determine the required diameter of a steel transmission shaft 10 m in length and of yield strength 350 MPa in order to resist a torque of up to 500 N-m. The shaft is supported by frictionless bearings at its ends. Design the shaft with a factor of safety of 1.5 according to (a) the maximum shear stress theory and (b) the maximum distortion energy theory
A hollow circular steel shaft has a 100-mm outside diameter and a 75-mm inside diameter. Calculate the allowable torque that can be transmitted if the allowable shear stress is 62 MPa. When the allowable torque is applied, calculate the shear stress at the inner surface of the shaft.
A hollow shaft consisting of a steel tube of 50-mm outer diameter is to transmit 250 kW of power while rotating at a frequency of 30 Hz. Determine - (7 points) (a) the tube thickness that should be used if the shearing stress is not to exceed 100 MPa. (3 points) (b) since in this simplified design calculation, the only stress considered is shear stress exerted on the shaft due to torques. Without taking into account of how power is...

Design factor is 25, an ulley rotate at 650 rpm. The shaft is to be made of SAE 4140 alloy steel. The pulley is made from 1095 Carbon seet The ompute the following: [I) Which of shaft, pulley and key has a [2] The...
A shaft with a diameter of 43 mm, is shown below On the right hand side at location D a wheel has a force F of 4824N applied. The diameter of this wheel is 150 mm. The torque produced by F is transmitted through the entire shaft to location A where the torque is reacted. There are no other constraints at location A. Bearings, are located at B and C, and provide radial constraint. The bearing at B also provides...
QUESTION 1 A portion of a shaft where gear is to be mounted has a diameter of 134 mm. The gear transmits 446 N.mm of torque. The shaft is to be made of SAE 1040 cold-drawn steel. The gear is made from SAE 8650 OQT 1000 steel. The key is made from SAE 1018 steel (Sy: 372 MPa; Su: 441 MPa) The width of the hub of the gear mounted at this location is 10 mm. Compute the Shearing force...
