Two masses m are attached to opposite sides of a rigid rotating shaft in the vertical plane. Another pair of equal masses mi is attached to the opposite sides of the shaft in the vertical plane as shown in figure. Consider m 50 m a=2mand al = 2.5 m For the system to be dynamically balanced, mi should be kg 20 mm, b 0.3 m, 211

A bolted joint has four bolts arranged as shown in figure. The cross sectional area of each bolt is 25 mm2. A torque T = 200 N-m is acting on the joint. Neglecting friction due to clamping force, maximum shear stress in a bo MPa 100 mm !
Consider a fully developed steady laminar flow of an incompressible fluid with viscosity u through a circular pipe of radius R. Given that the velocity at a radial location of R/2 from the centerline of the pipe is U1, the she the ss at HU1/R, where K is
