1.A single metallic crystal is oriented such that the normal to the slip plane and the slip directions are at angles of 50 and 40 degrees respectively, with the tensile axis. If the dislocations in the plane start moving when the resolved shear stress is 6.2 MPa, what is the tensile stress at which yielding occurs?
2.What is atomic packing factor? Which crystalline structures exhibit the maximum atomic packing factor values? Please provide detailed solutions, steps and explanations
A 1kg ball is dropped from the top of a cliff and falls with a constant acceleration due to gravity. Assume that effects of air resistance can be ignored.
Determine the moment of inertia of the shaded area about the following axis: a. x-axis b. y-axis show properly dimension figures.
A collar of weight m slideswithout friction on a horizontal rod between springs A and B. Thecollar is pushed to the left, compressing spring A 0.1 m. k of A is1.6 kN/m and k of B is 2.8 kN/m.
They each completely penetrate a homogeneous, confined aquifer, and pump at exactly the same rate, 5m^3/day. Prior to pumping, the piezometric head was 30m, the same as the thickness of the aquifer.
Crude oil (s.g.= 0.86, m =7.18*10-3 Pa*s) is to be carried at a flow rate of 0.25m3/s between two tanks with a difference of surfaceelevation of 9 m. The pipeline is smooth (e=0) and 90m long. What pipe size (diameter) is required?
Using a safety factor of two based on the stress, determine the maximum temperature the component must be exposed to for it to sustain the stress for at least 1000 days.
how many pounds of coal must be burned to keep one 100 watt light bulb lit for one hour. Assume efficiency of the power plant is 35%, the transmission losses are 10% fo the delivered poer, and the heating value of coal is 12,000 BTU/lb
A tire carries a 5,000-lb load and has a pressure of 100 psi. The pavement has a modulus of elasticity of 43,500 psi. A deflection of 0.016 inches is observed at a point on the pavement surface 0.8 inches away from the tire load.
