a simply supported composite beam 3m long carries a uniformly distributed load of intensity q=3.0kN/m. the beam is constructed of a wood member, 100mm wide by 150mm deep, reinforced on its lower side by a steel plate 8mm thick and 100mm wide. Find the maximum bending stresses(wood) and (steel), in the wood and steel, respectively, due to the uniform load if the modulus of elasticity are E (wood)=10 GPa for the wood and E (s)=210 GPa for the steel.
The owners wish to achieve an initial acceleration from rest of 22 ft/(sec^2) on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve this acceleration
A cylinder contains 3 kg of water and water vapor mixture in equilibrium at a pressure of 500 kN/m2. If the volume of the cylinder is 1.0 m3, calculate the following: a) Temperature of the mixture b) The volume and mass of the liquid
In the late 1990's the U.S. Army Corps of Engineers designed an experiment to model the flow of the Tennessee river downstream of the Kentucky Lock and Dam.
Determine the percent error n in replacing the sine and the tangent of an angle by the value of the angle in radians for angle values 5 degrees, 10 degrees, and 20 degrees. Explain the qualitative difference between the sine and tangent results.
The beam is subjected to a force F=825 lb in the direction, and is supported by a pin connection at point B and a rope attached through a pin connection at point A. Problem #1: Draw a complete FBD of the beam.
The ½ inch pipe was found to have an average friction factor of 0.0129 and the ¾ pipe had an average friction factor of 0.0209. The length of the pipes between the two manometer connections are 60 inches each.
Determine the strain components strainx, Strainy, and gammaxy, then sketch the deformed shape in the xy orientation, paying particular attention to the sign of the shear deformation.
The absolute viscosity and density of water are 1.4X10^-3 Pa-s and 998 kg/m^3, respectively. For a head loss of 0.1 m, determine the filtration rate (m/d) if the depth of this layer of sane is 0.1m
The casting has a mass of 3 Mg. Suspended in a vertical position and initially at rest, it is given an upward speed of V mm/s in 0.3s using a crane hook H. Determine the tension in cables AC and AB during this time interval if the acceleration is ..
A cutting 9 m deep is to be excavated in saturated clay of unit weight 19 kN/m3. The design shear strength parameters are cu = 30 kN/ m2 and fu = 0. A hard stratum underlies the clay at a depth of 11 m below ground level.
A cylindrical chimney,1 m in diameter and 2.5 m tall is exosed to a uniform 50km/hr wind at standard atmospheric conditions.End effects and gusts may be neglected.
