The figure above shows a shaft mounted in bearings A and D and having pulleys at B and C. The shaft is 20 mm in diameter and made of AISI 1020 CD steel. The forces shown acting on the pulley surfaces represent the belt tensions. The shaft is concerned with yielding and fatigue failure. [Stress analysis) (1) Draw the free body diagrams and find reaction forces at A and D in the xy and xz planes. (2) Draw the shear force and moment...
A countershaft carrying two V-belt pulleys is shown in the
figure. Pulley A receives power from a motor through a belt with
the belt tensions shown. The power is transmitted through the shaft
and delivered to the belt on pulley B. Assume the belt tension on
the loose side at B is 15 percent of the tension on the tight side.
Yield of the Shaft ?? = 560 ???
a) Determine the tensions in the belt on pulley B, assuming...
Please answer A and B.
The rotating solid stedl 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 drive gear acts at a pressure angle of 20. The shaft transmits a torque to point A of TA-340 N m. The shaft is machined from steel with Sy- 420 MPa and Sut-560...
Problems 1. (Subtotal: 21 points) A steady torque of 1500 Ibf in is transmitted by a machined shaft made of steel with an ultimate tensile strength of 100 kpsi. The transverse cross section at the location of a shoulder against which a gear sits is subjected to a bending moment which is a sinusoidal function of time with a maximum of 800 lbf-in. Furthermore, this cross section is the location for the maximum von Mises stress. The smaller diameter at...
4. Here is a similar problem with pulleys and shafts, complicated slightly due to the fact that there are forces in two planes, not just one, as previously. Dimensions in the figure are in mm. Some additional dimensions are: dahaft 18 mm 200 mm300 mm 300 400 Ts Te 150 d Assume bearings 0 and C are frictionless. Assume tensile forces are T = 200 N and Ti 40 N. Further assume steady-state operation. (a) On pulley A, suppose the...
