A pool player wants to bank ball B off of point A into the side pocket O. The ball has a diameter d = 2.25 in. and a coefficient of restitution e = 0.8 when colliding with the side of the table. Find the location of point A on the table by calculating the length a(distance b/w A and B). Treat the side of the table as immovable.
The outside and inside diameters of 75 mm and 63 mm, respectively. A strain gauge is placed on the outside of the hollow segment of the tube to measure normal strains in the longitudinal direction. assume E=73 GPa and Poissons ration v=0.33. strai..
What are the effects of hardness, hot strength and hot hardness and work hardening of work materials
At all other times, the wind velocity is zero. Determine for each case the ration of the total energy available from the wind to the total wind energy available at the mean velocity operating continuously
A rectangular channel 2.0 m wide carrying a discharge of 2.5 m3/s is to be fitted with a weir at its downstream end to provide a means of flow measurement as well as to cause heading-up of the water surface.
Estimate the buoyant force on 10'x10' by 2' deep balsa (SG=0.2) raft with you in it. How deep is it in the water. Be sure to draw well leveled schematic of the system.
Neglecting the effect of altitude of local gravitional acceleration, determine the vertical distance climbed. Assume an average air density of 1.18 kg/m^3.
the pin at B is attached to member ABC and can slide freely along the slot cut in the fixed plate. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when.
If the HCO3- alkalinity of a sample was 50 mg/l as CaC03, what would its alkalinity be in terms of NaCl equivalents
The total volume of the house is 650 m3 (assume that the volume is well mixed throughout). The radon source emits 250 pCi/s (A picoCurie [pCi] is a unit proportional to the amount of radon gas and indicates the amount of radioactivity of the gas)
The IIT components of ownership cost based on average annual value are: Tax-3%, Insurance -4%, and Interest-7%. a) What is the average annual value?
Water flows down a spillway at the rate q = 15 m^3/s into a horizontal channel where v1 = 20 m/s. Determine the depth of flow in the channel y2 that will casue the hydraulic jump to occur in the channel. Determine the headloss hL in the jump.
A perfectly mixed aeration pond with no recycle serves as the biological reactor for a small community. The pond receives 30m^3/d of influent with a BOD5 of 350mg/L that must be reduced to 20mg/L before discharge.
