1.Does the bending moment at the right hand side end of a beam always have to be zero (on a bending moment diagram)? Even when there is an external couple moment applied at that point?
2.air having a pressure of 40 psig and a volumen of 8 cuft expand isothermally to a pressure of 10 psig find theexternal work performed during the expantion.
3.This is a dynamics problem I could not sove it all. Thisproblem is on pg 57 of the dynamics section.
A package is dropped from the plane which is flying with aconstant horizontal velocity of va=150ft/s. Determine thenormal and tangential comonents of acceleration and the radius ofcurvature of the path of motion (a) at the moment the package isreleased at A, where it has a horizontal velocity of va=150ft/s,and (b) just before it strikes the ground at.
The problem has a graph showing a plane at 1500ft highwhich is point A and Va=50ft/s is moving horizontaly(forward). Point B is at the ground further from theplane, obviously at an angle and the package is falling on thisdirection.
4.a volumen of 20 cu ft of air at pressure of 50 psig is heated and expanded and to 30 cu ft and 40psig find the changes in the energy of air in jouls.
How much of a reduction in the automobile emission rate would be required to achieve the maximum eight-hour average NAAQS for CO at steady state 9ppmv (10.3 mg/m3)?
f the design speed of a multi-lane highway is 60 mph, what is the minimum sight distance that should be provided on the road if (a) the road is horizontal and (b) the road has a maximum grade of 5 percent
calculate the density and specific weight of carbon dioxide at a pressure of 300 kN/m^2 absolute and 60º C
Just below the point where a continuous discharge of pollution mixes with the river, the BOD is 10.9 mg/L and the DO is 7.6 mg/L. The river and waste mixture has a temperature of 20oC, a deoxygentation constant of 0.2/day
A fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4m/s. The pressure at the center of the pipe is 40KPa, and the elevation of the pipe's centerline above an assumed datum is 4.5m. Compute the total energy per unit weight of the ..
Calculate the viscous drag force on this plate, assuming boundary-layer flow with free-stream velocity of 15 ft/s and plate dimensions of L = 8 ft and W = 4 ft.
Two new rides are being compared by a local amusement park in terms of their annual operating costs. The two rides are assumed to be able to generate the same level of revenue (and thus the focus on costs).
The number of flaws on a sheet of aluminum manufactured by a certain process follows a Poisson distribution. In a sample of 100m2 of aluminum, 200 flaws are counted.
using stadia and inclined sights, the stadia top and bottom readings are 8.5ft and 6.21ft respectively, and the vertical angle is read as -8degress 42'. what is the horizontal distance.
a concrete dam retaining water has a specific weight of concrete of 23.5kn/m3, what is the factor of safety against sliding & overturning and pressure intensity on the base if coefficient of friction is 0.45.
Estimate the chronic daily intake of 1,1,1-trichloro ethane from exposure to a city water supply that contains a 1,1,1-trichloroethane concentration equal to the drinking water standard of 0.2 mg/L.
