Structure O A B C is built in at point O and supports forces from two cables. Cable E A D passes through a frictionless ring at point A, and cable O C G passes through a frictionless ring at point C. If the force in cable E A D is 800 lb and the force in cable O C G is 400 lb. determine the moment of all cable forces about point A
A circular disk rotates on a bearing at point A, and has a string BCD attached to it. The pulley at Cis frictionless, and the string supports a weight W = 10 lb. Determine the moment of the force in segment BC of the string about point A for any position of the disk where 0° ? ? ? 360°, and plot the moment versus ?. Neglect the size of the pulley.
Ends A and D of the two solid steel shafts AB and CD are fixed, while ends B and C are connected to gears. Knowing that a 4-kN(m) torque T is applied to gear B, determine the maximum shearing stress (a) in shaft AB, (b) in shaft CD.
Water in the amount of 1 lb is contained in a rigid closed tank. Initially the water has a quality of 0.4 at a pressure of 10 lbf/in2. Through a stirrer, work is provided to the water in the tank until the pressure quadruples.
A .2kg mass of argon gas fills a .05m^3 piston-cylinder volume at a pressure of 400 kPa absolute. The piston induced pressure is changed until the volume expands to twice its original value, while the temperature remains constant.
This problem models an insertion process. Block A (mA = 2kg) is acted on by a horizontal force F (F = 12 N). As A moves to the right, it gets pressed more and more tightly in the channel.
three bars each made of different materials are connected together and placed between two walls when temperature is t1
A small community wishes to construct an activated sludge wastewater treatment plant to treat their wastewater. the wastewater from the community has an average flow rate of 0.0022 m^3/s (190 m^3/day) and an influent substrate concentration of 250 mg..
payments of $1000 are to be made at the end of each year for the next 3 years. What is the present worth of the three payments if interest is 12% compounded monthly
A pile resists the tension developed by three stay cables for a major tent (Membrane) Structure. Assuming no bending is desired in the pile (no resultant horizontal component), what is the magnitude of the force S if the angle \thetaS = 30 degrees
A weightless piston is placed on the liquid surface and the water level stabilizes (also in the small tube) to a level of h. Next, a weight of 10 kg is placed on the piston causing the liquid in the small tube to rise.
A couple M of magnitude 18 Nm is applied to the handle of a screwdriver to tighten a screw into a block of wood. Determine the magnitudes of the two smallest horizontal forces that are equivalent to M
Compute departures and latitudes, linear misclosure, and relative precision for a five-sided, closed traverse. It is given that the aziumuth of AB is 74 degrees 31 minutes, 17 seconds, A = 105 degrees 13 minutes 14 seconds B = 92
A multiple-piston hydraulic jack has two output pistons, each with an area of 250 cm^2. The input piston, whose area is 25 cm^2, is concerned to a lever that has a mechanical advantage of 9:1.
