Senior Capstone Design Team 54 has been engaged to design a mechanical piece of test equipment to simulate the mechanical forces that a fused cutout will see during an electrical occurrence for MacLean Power Systems (MPS) of York‚ SC. The overall problem is that the mounting arm for the fused cutout is experiencing plastic deformation from the mechanical forces that are produced during an electrical occurrence. MPS hopes to eliminate the problem by acquiring a testing apparatus that will simulate

SOIL NAILING FOR STABILIZATION OF SLOPES Abstract: After its development in early 1980’s it become widely used in method of providing permanent and temporary support for earth‚ and stabilization of slope on many engineering projects in world wide. In starting of this period soil nailing was only performed on that project where geotechnical contractor provide this as an alternative to other soil improvements techniques. Now a days soil nailing is accepted only because of its performance and effectiveness

example: 1. Load-limited design – wire ropes 2. Energy-limited design – spring in pegs 3. Deflection-limited design – paperclips 1. Load-limited design – wire ropes Wire ropes function as a tie. Hence the constraint is to withstand a certain tensile stress before failing by fracture. σ_f=(CK_1c)/√(πa_c ) If the objective to maximize the allowable stress‚ then‚ the material indices is simply M=K_1c CES (Cambridge Engineering Selector) is utilized to plot a diagram of fracture

how different factors affect the amount of bending of the beam. The two variables that were tested were the amounts of weight and the position of the weight on the plank. Aim: To find out how weight and different placements of the weight affect the bending of the beam. Hypothesis: It is predicted that the wood will bend more if there is more weight on it. When the weight is positioned differently‚ it will affect the amount the beam bends. Introduction: A bridge is a structure built to span

If the maximum tension the cable can withstand is 2.4 ×103 N‚ what is the maximum mass of the load? 20 kg 4. A 75 kg painter stands on a uniform 5.0 m board of mass 16 kg supported horizontally by two ladders. Find the forces exerted by each ladder on the board. FR = 593N‚ FL = 299N 5.
