Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

4. For this series of 4 questions, two blocks, A and B, are connected using the cable and pulley system as shown. (The cable and pulley system is friction-less and weight- less.) The coefficient of kinetic friction between block A and the inclined plane is μ = 0. 2. Initially the blocks are moving but eventually come to stop. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 4) If block A weighs 100 lb and block B weighs 65 lb, and initially block A moves down the plane at a velocity of 7.1 ft/s, determine how far block A will move along the surface until it stops. Your answer must include 2 places after the decimal point and the proper unit. Take g = 32.2 ft/s². A Your Answer: Answer B units C D

hello, can you do a step by step solution with explaination for me thank you so much
You construct a version of the cart and bucket, but with a slope whose angle can be adjusted. You use a cart of mass 167 kg and a bucket of mass 57.0 kg. The cable has negligible mass, and there is no friction. What must be the angle of the slope so that the cart moves downhill at a constant speed and the bucket moves upward at the same constant speed? With this choice of angle, what will be the tension in the cable?
4 Figure Q4 shows a racing car with a mass of 975 kg that was tested for the maximum acceleration it could achieve. The centre of gravity G of the car is 0.55 m above the ground level and the dimensions a and b are 1.82 and 2.20 m respectively. The coefficient of static friction is 0.68. The car is rear wheel driven. a) Draw the free body diagram for the car. b) Draw the kinetic diagram for the car. c) Determine the maximum possible acceleration for the car and comment on the reaction force at the point A. d) Determine the maximum possible acceleration of the car if the powertrain is changed to a four-wheel driven mode. Assume that both front and rear wheels are about to slip. B b Figure Q4
This question is similar to the question above but read and calculate carefully. The situation has changed and the numbers have changed. Bonita Cart Bonita is again pulling a cart to the right. The cart used to be tied to a wall but now the rope has broken so the cart rolls over the horizontal floor without friction. Assume that the only forces on the cart are tension forces (including the force from Bonita), normal forces, and gravity with g = 9.81 m/s?. Bonita's shoes do not slide over the floor. Bonita has a mass of 52 kg. The cart has a mass of 45 kg. The mass of the rope is small enough to be ignored. Bonita is pulling the cart with a constant force of 283 newtons. Calculate the magnitude of the force that the cart exerts on Bonita. Note that the magnitude of a force is a positive quantity.
