The force Pis applied to the 60-kg block when it is at rest. Determine the magnitude and direction of the friction force exerted by the surface on the block if (a) P = 0. (b) P=227 N, and (c) P= 326 N. (d) What value of Pis required to initiate motion up the incline? The static and kinetic coefficients of friction between the block and the incline are s = 0.23 and Uk = 0.18, respectively. The friction force is...
Determine the horizontal equilibrium force P that must be applied to the handle. The bearings are properly aligned and exert only force reactions on the shaft. Determine the x, y, z components of force at the smooth journal bearing A. Determine the x, y, z components of force at the thrust bearing B. Part A A vertical force of 400 N acts on the crankshaft. (Figure Determine the horizontal equilibrium force P that must be applied to the handle. The...
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
