1.The rod is made of a-36 steel and has a diameter of .25 in. if the springs are compressed 0.5 in when the temperature of the rod is T=40F, determine the force in the rod when its temperature is T=160 F. K=1000lb/in. and length is 4 ft long.
2.(a) an equivalent force-couple system at C,
(b) an equivalent system consisting of a vertical force at B and a second force atD.
Write out the continuity and momentum equations that govern the surge travelling downstream. (Note: assume that the surge velocity exceeds the water velocity)
determine the pressure at stagnation point on the nose of the airplane. also determine the manometer reading h for the manometer attached to the static pressure tap within the test section of the wind tunnel if the air velocity
What superelevation rate would you recommend for a roadway with a design speed of 100 km/hr and a radius of curvature of 500 m? Assume f = 0.11.
An irregular piece of unknown ore weighs 7 lb in air and was found to weigh 5.6 lb in water when submerged.
A car travels along a circular path such that its speed is increased by a_t=0.5e^t(m/s^2) ,where t is in seconds. The radius of curvature of the path is 30m. Determine the magnitude of its velocity after the car has traveled s = 18m starting from r..
The segments of pipe and couplings used for drilling an oil well 15,000 ft deep are made of A-36 steel weighing 20 lb/ft. They have an outside diameter of 5.50 in. and an inside diameter of 4.75 in
Listed on cramster as ask. There is a car driving through water. Velocity is 12mph. Find h (max water depth) that will alow car to pass. List all assumption and calculations is the problem statement.
Two capillary tubes have radii of 1 mm and 0.5 mm respectively. They are placed in a liquid whose density is 0.80 g/cc and which completely wets the walls of the tube, i.e. theta = 0. The difference in height of capillary rise is 0.74 cm.
Ammonium (NH4+) is a weak acid with a pKa of 9.26. The dissociation is: NH+4 NH3 + H+. Calculate the mass of ammonium added to 1 L of water in order to obtain a pH of 4 at equilibrium.
