Neglect the diameters of the pulleys and determine the horizontal and vertical components of the pin reaction at C on member ED.Figure P2-4 2.5 For the spring assemblage shown in Figure P2-5, obtain the global stiffness matrix by the direct stiffness method. Let k(¹) = 1 kip/in., k(²) = 2 kip/in., k(3) = 3 kip/in., k(4) = 4 kip/in., and k(5) = 5 kip/in. 67 que Figure P 2-5 999 2 3 4 ffff 4

Figure P4-21 shows an anvil for an impact hammer held in a fixture by a circular pin. If the force is to be 500 lb, specify a suitable diameter for the steel pin if it is to be made from SAE 1040 WQT 900. 4-21
- 1. Calculate the degree of freedom of the following mechanism shown in Fig. 4-1. If there are multiple pin joints, passive degree of freedom or redundant constraints, mark them in the figure. Fig. 4-15. In the mechanism shown in the figure, a-150mm,b-155mm,c%3D160mm,d%3D100mm, e=350mm. Analysis whether the mechanism has the quick-return motion when AB acts as the driving link and slider E acts as the driven link (If it has, redraw a figure to find the coefficient of travel speed variation K)? Is there a change if CD acts as the driving link? Explain that using the graphical method. Bo e E DThe figure shows the rear rotating axle of a 4-wheel wagon with the same FRONT AXLE design and REAR AXLE design. The wagon moves at a constant speed and the diameter of the wheels carrying the axle is D=512 mm and the circumferential speed=3.1 m/s. Due to the load (m) on the wagon, a force of 16574 Newtons acts in the vertical direction. ALSO, a horizontal force of 21% of the vertical load acts on the wagon laterally (horizontally) in bends. It is planned that the bearings of the axle will be bearing 6008 deep groove ball bearings. Calculate the life of bearing A in hours.The radial effect of lateral loads will not be taken into account in the bearing force calculation. Fo.Fa/Co = 1.38 Pi=3.14
