Two force, wherever you point it, it stays straight. These forces are equal in magnitude and opposite in sense, and have the same line of action. if i have a member with two points on it and forces acting on those points, it will be on the same line of action as those points. They will have opposite sense and same magnitude. They will have some angle, which you will know. this cuts it down to a single force that you have to solve for, regardless of what type of member it is. Prove that the forces are equal and that the lines of action are along an angle theta. HINT: Use to do equations of equilibrium.
The company would like to distribute the songs between the two CDs such that the used space on each CD is about the same. Formulate the problem as an IP, and find the optimal solution.
Plot the magnitude of the force exerted on the gate by the brace as a function of the angle of the gate, , for . Assume the weight of the gate is negligible.
Typical water supply at a faucet in any building is conveyed in copper pipe that is ½" in inside diameter, with a wall thickness of 0.040". If the water pressure is 50 psi and the valve is closed (meaning that water is not flowing)
At a parking lot, vehicles arrive according to a Poisson process and are processed (parking fee collected) at a uniform deterministic rate at a single station. The mean arrival rate is 4 veh/min and the processing rate is 5 veh/min.
The line of sight of a level falls at a rate if 0.122ft/ 100 ft when the level bubble is centered. A backsight of 4.782 is taken on point A, which is at 75 ft from the level. the elevation of a is 425.238 ft.
if a ball is dropped from a height of 800 cemtimeters, and the impact velocity is 41 feet per second, determine the value of gravity in units of meters per second.
determine the range from the SV to the REC in GPS; using codes C/A and P and also waves (L1 and L2). How does two of the below from the list have an effect on the codes and waves
Water flows through a horizotal 45 deg reducing bend with a 36 inch. diameter upstream and a 24 inch diameter downstream, at the rate of 20 cfs under a pressure of 15 psi at the upstream end of the bend. Neglecting head loss in the bend, calculate..
A 45-cm-thick, 300-cm-high lightweight concrete masonry unit wall lies on a 20-cm-thick lightweight plain concrete slab. The 20-cm wide slab is supported by a reinforced concrete beam, which is placed on top of two columns (simply supported beam).
A development is being planned within a 250-acre watershed. The present land use is 120 acres of pasture, with soil type B(CN=61), and the rest soil type D (CN=80). The Tc is 54 min. and the 2-year, 24-hour storm depth is 4 in.
A 3-mm thick panel (1 m x 1 m) of aluminum alloy (k = 177 W/m. K, Cp = 875 J/kg. K, and p(rho)= 2770 kg/m3) is heated in a large oven with air at T = 175oC and a convective heat transfer coefficient of h = 40 W/m2.K.
