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
A 20-mm diameter rod made of a ductile material with a yield strength of 350 MPa is subjected to torque of 100 N.m and a bending moment of 150 N.m. An axial force is then gradually applied. Determine the value of force when the rod begins to yield..
