Solve in SI units. A gear reduction unit uses the countershaft shown in the figure. Gear A receives power from another gear with the transmitted force FA applied at the 20ᵒ pressure angle as shown. The power is transmitted through the shaft and delivered through gear B through a transmitted force FB at the pressure angle shown. a) Determine the force FB, assuming the shaft is running at a constant speed. b) Find the magnitudes of the bearing reaction forces,...
3- The shaft shown in the figure rotates with constant angular velocity and is transmitting a torque from gear B to gear C through the forces Exo and Ez as shown. The shaft is subject to combined bending and torsion due to the forces shown. The weights of the shaft and pulleys may be neglected and the supports can exert only concentrated force reactions. The radius of the gear at B is 50 mm and that at C is 75...

I. The countershaft shown in the Fig Q1 has two spur gears mounted on it with teeth cut wi a 20 pressure angle. The shaft (grooved) is to be made of cold-drawn AISI 1040 steel havin Sut 779 MPa and S,-593 MPa, an elongation of 19% and HB-262. You are asked to size the shaft for safe operation according to DE-Elliptic criterion by using a factor of safety of 2.5 and a reliability of 99 percent. The stress-concentration factors for...

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...
