1.A particle moves along the positive x-axis with an acceleration in meters per second squared which increases linearly with x expressed in millimeters, as shown on the graph for an interval of its motion. If the velocity of the particle at x = 45 mm is 0.57 m/s, determine the velocity at x = 220 mm.
2.Given simply supported beam with an overhang. The beam is 12 inches wide by 24 inches deep, and the slab is 6 inches deep. use a roof live load of 20 psf, and a concrete density of 150 pdf. the beams are spaced 15 feet apart. the total beam length is 30 feet, with 24 feet between supports and a 6 foot overhang. plot the shear and moment diagrams for the beam
Calculate the compacted cubic yards per hour if a compactor with a 5-ft drum width travels at 3 mph over a 10-in. lift of aggregate base course with 4 passes required to meet density specifications under average operating conditions.
Given the stationing in meters as (4+56) for the PC of a horizontal curve of radius R=1200 meters and angle I=22°. The azimuth of the line PC to PI as AzPC-PI = 155° 30'. A point P is to be located on the curve at stationing of 7+00.
Laboratories containing dangerous materials are often kept at a pressure slightly less than ambient pressure so that contaminants can be discharged through an exhaust system rather than leaked through cracks and around doors to other parts of the ..
find the maximum allowable force P if the maximum allowable bearing stress on 6 pins holding 2plates together is σ all=10 MPa, and the maximum allowable shear stress is τ all =25 MPa
Uniform deposits were made on January 1 of 1991, 1992, 1993, and 1994 into a fund intended to provide $1000 on January 1 of 2005, 2006, and 2007. What were the size of these deposits
Vision Technologies Inc., is a small company that uses ultra-wideband technology to develop devices that can detect objects (including people) inside of buildings, behind walls, or below ground.
The potentiometric surface elevations at two observation wells 1000 m apart are 52.35 m and 56.90 m. If the horizontal hydraulic conductivity of the auquifer is 25 m/ day determine the specfic discharge, and average linear veolicity of the flow as..
a tower is surrounded by a wall that is 10 m high and 30 m away from the base of the tower. compute the length of the shortest ladder that can stand outside the wall and lean against the tower.
A flat bar of cross section 20mm by 70mm elongates 4.0mm in a length of 2.0m as a result of axial load. If the elastic modulus is 199x106 kN/m2 and Poisson's ratio is 0.25 for the material, find the axial load and the total change in each cross secti..
A fluid of density rho flows steadily downward between the two vertical, infinite, parallel plates. The flow is fully developed and laminar. Make use of the Navier Stokes equation to.
If the time required to pay for parking is exponentially distributed with a mean of 15 seconds, find the average time in system.
Let the cross - sectional area of the tube be given by A and the position of the cylinder by s , and assume that the compressed gas is an ideal gas at constant temperature so that the pressure P times the volume is a constant
