Each of the plates A, B, and C have a mass of 10 kg. Plate A is on the bottom, plate B is in the middle, and plate C is on the top. Plate A is being pulled to the right with a force of 15 N, Plate B is being pulled to the let with a force of 100 N, and Plate C is being pulled to the right with a force of 18 N. The coefficients of static and kinetic friction are 0.3 and 0.2, respectively, between each of the plates and between plate A and the ground. Determine the acceleration of each plate.
A particular soil has a total (moist) unit weight of 122 pcf and a dry unit weight of 101 pcf. The specific gravity of soil is 2.70. Calculate the water content and degree of saturation.
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
if 25 acres of land recieved 3.5 inches of water from the irrigation district, determine volume of water on the land in acre-ft
Input parameters for the function should be the lower and upper bounds of the root. Obtain reasonable values for the lower and upper bounds by graphing the function in Excel. Turn in your code for the VBA function.
The elevation of the lowest bottom of the structure is at 1470 feet. Calculate the maximum length (feet) of the parabolic curve required to meet the given conditions.
Starting from rest, a 4.0-kg body reaches a speed of 8.0 m/s in 2.0 s. What is the net force acting on the body?
Write the mass balance equation for a completely mixed lake with an impulse input of mass,M, added at time t=0. Assume the lake is of constant volume, V, with continuous outflow, Q, and a conservative substance.
A pool of benzene is ignited on the floor of a large industrial building. The total area covered by the Kerosene pool is 6 meters square (Note that this is considered a large pool D>0.2 meters). Combustion efficiency is 70%. Estimate the plume mas..
Assuming Stokes behavior, calculate the terminal settling velocity in standard air for the following particles: (a). diameter = 10 micrometers, specific gravity =1.2; and (b) diameter = 4 micrometers, specific gravity = 2.0.
a temperature probe moves with the velocity 2i+2j-3k through air. the temperature of air changes as T(x,y,z,t)=(2x^2-3y+z^3)cos(at). Find the rate of change of temperature measured by the probe.
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
