1.Using the principle of transmissibility, the force F_evec can be slid along its line of action from point A to any other point along its line of action. What points along the line of action of the force F_evec would simplify the calculation of M, the magnitude of the total moment due to the force F_evec about point O?
2.Draw the influence line for the shear at point B. Plot numerical values every 5 ft. Assume the support at A is a roller and C is fixed. EI is constant.
3.Steam at 800 kPa and 300 C is bled off from a large supply line, passed through a valve, and allowed to enter an initially evacuated, uninsulated tank with a volume of 0.3 m3. When the pressure in the tank reaches 100 kPa, the valve is closed. The temperature in the tank when the valve is closed is reported to be 150 C. Determine whther this process is possible (Assume T0=25 C).
A force P is applied to bent rod ABC, which may be supported in four different ways. In each case, if possible, determine the reactions at the supports.
Calculate the undrained shear strength at a depth of 120 ft below the mudline. Calculate the undrained shear strength at a depth of 120 ft below the mudline if the soil has an OCR of 2.5 .
For an intermediate beam in 3 bays by 3 bays (each bay is 20' by 20') floor plan, draw the envelope shear and moment diagrams taking into account effect of pattern loading.
why the highest head of the water in the excavation is mathematically guaranteed to occur on the edge of the excavation. explain in mathematical and/or physical.
A room in a single-story building has three 2.5 x 4 ft double-hung wood windows of average fit that are not weather-stripped. The wind is 23 mph and normal to the wall with negligible pressurization of the room.
To protect the channel from erosion, the normal flow velocity for the design discharge has to be reduced to 7.0 fps or below, and the flow Froude number must be reduced to 0.80 or below.
Transportation network, A power generator at a dam can send 300 megawatts to substation 1, can send 200 megawatts to substation 2, and can send 250 megawatts to substation 2
At the end of 15 years, the first motor will have a salvage value of $50 and the second motor will have a salvage value of $100. consider the MARR to be 8%. (note : 1HP=0.7457 kw). Determine which motor should be installed based on the PW criterio..
What is the porosity of a sphere of 1 ft diameter packed inside a cube of 1 ft on each edge. What if the spheres are six inches in diameter. What if the spheres are one inch in diameter.
a simply supported beam with a span of 8m is to carry, in addition to its weight, a superimposed dead load of 18kN/m and a live load of 30kN/m both over the entire span.
A small chunk of the original sample had a wet weight of 140.9 grams and weighed 85.2 grams after drying. Compute the water content, using the correct number of significant figures.
The C-S-H gel can come in a variety of chemical structure forms. If it has a cement notation form of C3 S2 H8, what is the periodic table form of this C-S-H gel. What would be the balanced equations for C3 S and C2 S when hydrated into this form
