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.

Question

A model airplane of mass 0.750 kg flies in a horizontal circle at the end of a 60 cm control wire, with a speed of 35 m/s. Compute the tension in the wire, if it makes a constant angle of 20.^o with the horizontal. The force exerted on the airplane are the pull of the control wire, the gravitational force, and aerodynamics lift, which acts at 20^oinward from the vertical

Mason is is trying to keep a door open using a door stopper. That door is solid, and it has a mass of 18.3kg. The door closer is connected 26.2cm away from the hinge, and pulls with a force of 123N. The door stopper provides a static friction force of 13.2N, and a kinetic friction force off 11.8N. Find the angular acceleration (as a vector) of the door.

A model airplane of mass m flies with a speed |v| in a horizontal circle at the end of a control wire of length L. Circular path of airplane Wire a) Draw a free-body diagram for the force acting on the plane. Assume that the aerodynamic lift force acts in a direction perpendicular to the wings of the airplane, and that the wire is at an angle below the horizontal. b) Calculate the lift and tension forces if m = 0.750kg, v = 35.0m/s, L = 60.0m and e = 20.0°.
Let us say that we have a ladder with its own length (L) and its own mass (m) this ladder just so happens to make a (θ) degree angle with a wall. The center of mass of this ladder is 1/3 of the way up from the bottom (it gets narrower towards the top). A person of mass M then decides to climb the ladder until he comes to the halfway point. Wall has no friction but the ground has on the ladder.. a) Draw this situation and label forces so you may set up the statics equations. b) Find the force on the ladder due to the ground (both x and y components) and the force on the ladder due to the wall.
In the situation shown in image, let u be the angle of the slope and suppose there is friction between the cart and the track. You find that if the cart and bucket each have the same weight w, they remain at rest when released. In this case, what is the magnitude of the friction force on the cart? Is it less than, greater than, or equal to w?
