If a force (p) of ( 7.8 ) N causes the 30 mm diameter shaft to slide along the lubricated bearing with a constant speed (y) of 1.4 m/s, determine the hydraulic shear stress (T) and dynamic viscosity ( Mu ) of the lubricant .Also , find the constant speed Ynew in m/s of the shaft when the magnititude of P is tripled value .The gap between the bearing and the shaft is1 mm and the width of the shaft (x) is 23 mm as shown in the figure bellow. 1.The hydraulic shear stress ( Tau) is------- The answer in kPa? 2. The value of the dynamic viscosity ( Mu ) in Pa.sec is? 3. The new speed of the shaft when the value of the force P has been tripled is The answer in m/sec?
