(a) draw the free-body diagrams for the entire assembly (or structure) and each of its parts. Neglect friction and the weights of the members unless specified otherwise. Be sure to indicate all relevant dimensions. For each problem,
(b) determine the total number of unknown forces and the total number of independent equilibrium equations.
a four-lane freeway two lanes in each direction is on mountainous terrain with 11ft lanes a 5ft right-side shoulder
A chair weighing 150 rests on a level floor that is not frictionless. A man pushes on the chair with a force = 43.0 that is directed at an angle of 34.0 with the horizontal. Assume that the chair is stationary but is on the verge of sliding.
a vertical curve on this highway connects +1% and +3% grade and is 420ft long. if a horizontal curve on highway is on a two-lane section with 12 ft lanes and has a central angle of 37 degrees and a superelevation of 6%, what is the length of the h..
The velocity of a body is given by v(t) = 2t+t3. The body starts from rest at time t = 0 at position s(0) = (2,-10). What are the position and acceleration of the body as functions of time At what time, t, does the body cross the X-axis
what are the three meterials based on the predominant types of bond and what are the predominant types of bond in each category
The boiling water passes through copper pipes that have a wall thickness of 4 millimeters and a surface area of 0.12 square meters per meter length of the pipe. Find the total length of pipe (there are actually many pipes in parallel)
A steady-flow compressor is used to compress helium from 15 psia and 70oF at the inlet to 200 psia and 600oF at the outlet. The outlet area and velocity are 0.01 ft2 and 10 ft/s
two solid cylindrical rods are joined at B and loaded as shown rod AB is made of steel(E=200 GPa) and rod BC of brass ( E = 105GPa) determine a) the total deformation of composite rod ABC, b) the deflection of point B
