HAB A В µCG µBC If the picture does not load, click here. Three blocks are positioned on an incline of 0=24° as shown. A force of P is applied to Block C and a wire attaches Block A to the wall, preventing that block from moving. The mass of Block A is ma=35kg, the mass of Block B is mg=53kg, and the mass of Block C is mc-47kg. The coefficient of static friction between Block A and Block B is UAB=0.18, between Block B and Block C is uBc=0.28, and between Block C and the ground is ucG=0.40. Determine the maximum value of P before any slipping takes place. Write your answer for P in N units to 2 decimal places in the box below. Hint #1: Recall that the shear (tangential) force across a sliding surface can never exceed F = mu * N Hint #2: You will need to find a value for P based on the condition that one block slips AND a value for P based on the condition that multiple blocks slip. The final answer will be the lesser of the two values. Values: HAB=0.18 0=24° ma=35kg HBC=0.28 mB=53kg…

3. During the design of spherical pressure vessel for space programs, a primary criterion is the mass of the vessel (which determines how much it costs to put it into the orbit). Given the stress in a thin walled spherical vessel is tensile and given by: Pr 2t where P is the pressure in the vessel, r is the radius and t is the wall thickness. For safety, materials will experience stress smaller that yield stress by a safety factor N. 10-1 Show that the minimum mass of the pressure vessel will be m= 2Νπ Pr' where p is the density of material. ys Given the data in Appendix B1 and B4 in the textbook, select the material (from following table) that will result in the lightest possible pressure vessel.
