The tower crane is used to hoist the 2-Mg load upward at constant velocity. The 1.5-Mg jib BD , 0.5-Mg jib BC , and 6-Mg counterweight C have centers of mass at G1 , G2 , and G3 , respectively. Determine the resultant moment produced by the load and the weights of the tower crane jibs about point A and about point
A manometer of water reads a height of 20cm at a temperature of 15 degrees C. If the diameter of the manometer tube is 1mm, what is the static height reading
The portable floor crane in the automotive shop is lifting a 420 lb engine. For the position compute the magnitude of the force supported by the pin at C and the oil pressure p against the 2.70 in. diameter piston of the hydraulic cylinder unit AB..
Calculate the force (in Kn) a punch press must exert if it is to punch out a large washer from a strip of 5-mm thick sheet steel with an ultimate shear strength of 400 MPa. The washer dimensions are as follows: hole diameter is 27 mm. outside diam..
The average rate of flow measured in a gage at the outlet of the watershed was 30 m^3/sec. Estimate the water losses due to the combined effects of evaporation, transpiration, and infiltration due to ground water.
Air enters an adiabatic nozzle steadily at 300 kPa, 200?C, and 30 m/s and leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 80 cm2. Determine (a) the mass flow raw through the nozzle, (b) the exit temperature of the air, and (c) the e..
(a) How is raw pig iron extracted from iron oxide ores (b) Write a typical chemical reaction for the reduction of iron oxide (Fe2O3) by carbon monoxide to produce iron.
The company engineer decides that this is too good, that it is not necessary to be this efficient, and proposed that part of the flue gas be bypassed around the electrostatic precipitator so that the recovery of fly ash (particulates) from the flu..
A sand sample has a porosity of 38% and specific gravity of solids of 2.66. Find the void ratio and wet unit weight in lb / ft3 if the degree of saturation is 35%.
Give one possible characteristic or property of sanstone and of the quartzite that made you decide not to select it for your concrete project?
The air above the liquid is under a pressure of 5 psig, and the specific gravity of the liquid in the tank is 0.80. If the rectangular gate is 6 ft wide and if y1 = 1 ft and y2 = 10 ft, what force P is required to hold the gate in place
If the internal pressure of the aircraft interior is 100 kPa, what is the outward force on a window. the window is flat and has an elliptical shape wiht lengths of 300 mm along the major axis and 200 mm along the minor axis.
Create a VBA function that will return the root of the function e-x -x = 0 using the Newton-Raphson method. The input parameter for the function should be the initial guess for the root. Turn in your code for the VBA function.
