A 6-m telephone pole weighing 1600 N is used to support the ends of two wires. The wires form the angles shown with the horizontal and the tensions in the wires are, respectively, T1 = 600 N and T2 = 375 N. Determine the reaction at the fixed end A.
Assume the stress is uniform within the sample (the stress tensor is the same at every point), and therefore the only stress is normal in the direction of the force. What's Young's modulus for this material?
A vertical bar is known to have dimensions 100" by 1" by 4" priorto application of a load, to have elastic modulus equal to107 psi, and to have a Poisson's ratio equal to 0.3.Suppose the bar is built in at the bottom and a mass of unknownweight is mo..
A spherical drop of water has r = .1mm . If the surface tension of water is 72 dynes/cm, calculate the pressure difference across the interface.
A footing 3m X 3m carries a pressure of 500 kN/ m2 at a depth of 1m in a sand substrate. The saturated unit weight of the sand is 20 kN/ m3 and the unit weight above the water table is 18 kN/ m3
Calculate the stagnation temperature and pressure for the following substances
Consider a cylindrical nickel wire 2.0 mm in diameter and 3 x 10^4 mm long. Calculate its elongation when a load of 300 N is applied. Assume that the deformation is totally elastic.
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
what value for Fy are the two forces F1=4i+Fyj+20K(N) and F2=8i-5j+7k(N) perpendicular to each other
A community had a population of 200,000 in 1995 and it is expected that this will increase to 260,000 by 2010. The water treatment capacity in 1995 was 165 ML/day. A survey showed that the average per capita water use rate was 700 L/(person.day). Est..
