Figure S8.3shows a pin-jointed frame with a vertical load of 10 kips applied to node 1. A model is constructed to a linear scale factor of lp/ lm = kl = 10. In the model, member 47 is shortened by 0.5 in and the vertical displacement of node 1 is 0.43 in. Determine the force in the prototype in member 47 caused by the 10 kip load.
a new space age development corporation in wichita kansas has borrowed a sum of $4M from a friendly bank at an interest rate of 9%. the company has also borrowed another $1M from other sources at an interest rate of 8%.
Water flows steadily through a horizontal 30 degree upward bend. The inlet diameter is 0.3 m, the velocity is 12 m/s, and the pressure is 128 kpa gage. The outlet diameter is 0.38 m and the pressure is 145 kpa gage.
On a shovel/truck operation the production of the shovel is 293 BCY/h and a job efficiency of 0.75. The trucks used have a capacity of 12 BCY and have a cycle time of 45 min.(excluding loading).
Suppose that the acceleration of the train during the interval time from t=2 to t=4 s is a 2t m/s^2, and at t = 2 s its velocity is v = 180 km/hr. What is the train's velocity at t = 4 s
Gate ABC in Fig is a quarter circle 8 ft wide into the paper. Compute the horizontal and vertical hydrostatic forces on the gate and the line of action of the resultant force?
The motion of the outer frame B is given by xB = b sin ωt. For what range of the driving frequency ω is the amplitude of the motion of the mass m relative to the frame less than 2b?
Water flows past a triangular flat plate oriented parallel to the free stream as shown. Integrate the wall shear stress over the plate to determine the friction drag on one side of the plate. Assume laminar boundary layer flow.
The pipe shown is subjected to a force of magnitude F = 800N. Determine the angle θ between F and the pipe segment BA, and the magnitudes of the components of F which are parallel and perpendicular to BA.
A moist soil sample weighing 22.2 N has a moisture content of 20%. How man N of water must be added to the sample to increase the moisture content to 30%
Taking the heat of vaporization of water to be 2450 kJ/kg, determine the contribution of showers to the latent heat load of the air conditioner per day in summer.
Terry wants to purchase a used car for $8000. The dealer offered to finance the deal at 8.5% APR for 4 years with 10% down payment. Terry's bank will provide a loan at 7.8% for 3 years, but wants a 20% downpayment.
Water in a piston/cylinder is at 90?C, 100 kPa, and the piston loading is such that pressure is proportional to volume, P ??CV. Heat is now added until the temperature reaches 200?C. Find the final pressure and also the quality if in the two-phase..
