A cross section of a rotating bearing is shown. The spherical member rotates with angular speed omega, a small distance, a , above a plane surface. The narrow gap is filled with viscous oil having mu = 1250 cp. Obtain an algebraic expression for the shear stress acting on the spherical member. Evaluate the maximum shear stress that acts on the spherical member for the conditions shown. (Is the maximum necessarily located at the maximum radius?) Develop an algebraic expression (in the form of an integral) for the total viscous shear torque that acts on the spherical member. Calculate the torque using the dimensions shown. (omega=70rpm, R=75mm, a=0.5mm, R0=20mm
If it is known that the value of the stress exponent n for this alloy is 8.2, compute the steady-state creep rate at 1300 K and a stress level of 89 MPa.
find Torque at O2, and forces at O2, A and B, also calculate shaking force and shaking torque. MEE40003- Machine Dynamics
