A block of weight W, attached to rigid linkage AB, rests on conveyor belt moving to the left as shown. Determine the magnitude of horizontal force P that should be applied to the belt to maintain the block's motion to the left. Neglect the weight of the rigid linkage AB. The coefficient of kinetic friction between the box and the conveyor belt is μk. Block of weight W conveyor belt Rigid

Write TRUE is the statement/s is True. If the statement is false, identify the word/s that makes the sentence incorrect and write its corresponding correct answer.  1. High cutting temperature is undesirable because it reduces tool life, produces hot chips and can cause inaccuracies in tool dimension due to thermal expansion. 2. Cubic boron nitride does chemically react with iron and nickel. 3. Nose wear is usually caused by rubbing of the tool along the machined surface of the workpiece.

04 05 a Explain the reasons for the following: 1- The pure aluminum and the copper are generally rated as easy to machine 2- In ultrasonic machining, the stress produced by the impact of abrasive particles on the workpiece surface is high. 3- In rolling process, the coefficient of friction must be sufficient. 4- Difference in solidification between casting and welding processes. 5- Why is it desirable to use energy sources for welding that have high heat densities? 6- Why there might be a change in the density of a forged product as compared to that of the cast blank. D. A cylindrical workpart with D=2.5 in and h=2.5 in is upset forged in an open die to a height = 1.5 in. Coefficient of friction at the die -work interface = 0.10 The work material has a flow curve defined by: K= 40,000 lb/in' and n-0.15. Determine the instantaneous force in the operation (a) just as the yield point is reached (yield at strain = 0.002), (b) at height = 2.3 in. (c) h= 1.9 in, and (d) h = 1.5 in. a List…

2) A washer is going to be manufactured by cutting operation out of 2024ST aluminum alloy sheet that has a thickness of 2.5 mm. The outside diameter of the washer is 25.0 mm, and the inside diameter is 12.0 mm. Make a rough sketch, define the geometries to be used and determine a. The punch and die size for the blanking operation b. The punch and die size for the punching operation c. The force required performing the blanking and punching operation simultaneously. The aluminum has a tensile strength = 300 MPa.
