A cylindrical specimen of a metal alloy is stressed in compression. if its original and final diameters are 40.00mm and 40.10mm respectively, and its final length is 120.00mm, compute its original length (L1) if the deformation is totally elastic. The elastic modulus (E), shear modulus (G), and Poisson's Ratio (v), for this alloy are 65.5GPa, 25.4GPa, and 0.30 respectively. Express your answer in [mm] to 2 decimal places.
the velocity varies linearly with time throughout the nozzle. the velocity at the base is 1t and at the tip is 4t. what is the local acceleration midway along the nozzle when t=2s
A froth flotation process is used to concentrate copper ore. It is a two stage process with a rougher stage followed by a cleaner stage. The cleaner tailings are returned to the rougher flotation.
Determine the time required for a car to travel 1 km along a road if the car starts from rest, reaches a max speed at some intermediate point, and then stops at the end of the road. the car can accelerate at 1.5 m/s^2 and decelerates at 2 m/s^2
