Find the torque (in-lb) necessary to tighten to 90 percent of the proof strenth, assuming cadmium plated threads. If the pressure vessel is pressurized to 500 psi, determine the total load per bolt.
Calculate the force exerted by the water in the pipe on the gate, and the distance GP between the centre of the gate, G, and the centre of P;
Modern vacuum pumps make it easy to attain pressures of the order of 10?13atm in the laboratory.At a pressure of 8.35×10?14atm and an ordinary temperature of 291.0K , how many molecules are pres
A large cylindrical tank contains 0.790m3 of nitrogen gas at 20.0?C and 7850Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed.What will be the pressure i
Three charged particles are fixed to an x axis: Particle 1 of charge q1 = 2.1e-8 C is at position x=20 cm and particle 2 of charge q2 = 2.00q1 is at position x = 30 cm, particle 3 of charge q3 = -4.00
Express the image distance si of a convex mirror in terms of the object distance so and the radius of curvature of the mirror R. Keep in mind that the focal length is considered negative for a convex
Estimate the thickness of each absorber required to attenuate a 100 keV photon beam by a 99.99 %.Which absorber material would be ideal for building a wall to shield you from the photons? Why?
A diagnostic tube has a target with a length of 10 mm. The electrons are focused along a strip of the anode 2.5 mm wide.At what angle (in degrees) should this strip be placed to yield an apparent
A sea diver's suit has a thickness of 5 mm and is made of a material with thermal conductivity of 0.05 W/mK. If the diver's skin is 33°C and the water temperature is 5°C and the heat tran
Show that the angular magnification m(theta) is also given by the equation: m(theta) = -f(objective) / f(eyepiece)
An upright object is placed a distance in front of a converging lens equal to twice the focal length (f1) of the lens. On the other side of the lens is a converging mirror of focal length f2 separated
In an eye that is farsighted, the eye focuses parallel rays so that the image would form behind the retina. In an eye that is nearsighted, the image is formed in front of the retina.How would you desi
