Each of the sandbags piled on the 250-lb uniform beam weighs 12 lb. Determine the support reactions at A and C.
Contain at least one two-force member. Solve by utilizing the two-force principle, where appropriate. If the weight of a body is not specifically stated, it can be neglected. Determine the clamping (vertical) force applied by the tongs at E.
A spring AB of constant k is attached to a support A and to a collar of mass m. The undeformed length of the spring is l. Knowing that the collar is released from rest at x = and neglecting friction between the collar and the horizontal rod, determin..
At the same instant the frame h, not the horizontal blade, rotates about a vertical axis with a constant angular velocity w=0.9 rad/s, measured relative to h
Define the specialization/concentration of your field. Describe the word ACRONYMS and list the acronym for your expected degree. e.g. CONS for Construction Technology.
A rectangular blade weighing 0.02 lbf is kept in the surface of water (sigma=0.073 N/m) solely by surface tension forces. What is the minimum perimeter of that the blade must have so that this is possible
Water in a piston/cylinder at 400?C, 2000 kPa is expanded in a reversible adiabatic process. The specific work is measured to be 415.72 kJ /kg out. Find the final P and T and show the P-v and T-s diagrams for the process.
Determine the reactions on the beam. The support at B can beassumed to be a roller.
determine the maximum torque T that can be applied according to the maximum-distortion-energy theory. Use a factor of safety of 1.5 against yielding.
Diesel fuel has an average chemical formula of C12H23 and a density of 6.45 lb/gal. Calculate how many lbs of CO2 are produced per gallon of diesel burned (assume complete combustion).
Assuming that the average stack gas velocity is 10.0 m/s and stack is circular with a 3.0 meter diameter, calculate the mass emissions rate of NO2 in kg/day.
Calculate the super-elevation required for a horizontal curve on a two-lane, two- way highway with 60 mph design speed, and a 1200 ft. radius curve. What is the required length of the spiral curve?
Two steel rods with fixed supports at A and C are attached by a rigid flange at point B and a downward load of 120 kN is applied to the flange. The upper rod has a cross section of 800 mm^2 and the lower rod has
