The 90lb door has its center of gravity at G.
A)Determine the components of reaction at hinge A if hinge B resists only forces in the x and y directions and A resists forces in the x,y,z directions.
B)Determine the components of reaction at hinge B if hinge B resists only forces in the x and y directions and A resists forces in the x,y,z directions.
When in use, a fishing rod can be approximated to act as a cantilevered beam. Assume that the force (P) is applied to the end of the beam by a fish while the fisherman rigidly holds the other end of the beam.
Consider a wide flange steel beam of size W10x60 subjected to a negative bending moment of 24 kip ft. Calculate the maximum compressive and maximum tensile stresses and indicate where the stress will be tensile and where compressive.
The slabs are to be built integrally with the end supports, which are spandrel beams. fy = 60,000 psi, fc' = 4000psi normal-weight concrete. Clear spans are 15 feet, 18 feet and 15 feet. with the longitudal span of 38 feet.
An industry discharges PCE (tetrachloroethene, tetratchloroethylene, or perchloroethylene) into a small, well-mixed lake. The influent concentration is 0.4mg/L and the hydraulic residence time of the lake is 5days.
If the average velocities in the 0.15 m and 0.2 m diameter pipes are 2 m/s and 3 m/s respectively, then find the average velocity in the 0.3 m diameter pipe
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?
The volume of a sphere is V=4/3pir^3. Prepare a table of volume versus radius which allows the radius to vary from 2.0 to 10.0 cm in 1 cm increments. Plot the data as a graph on log log paper showing the volume to radius relation
If the mean and variance of discrete random uniform random variable X, are E(X) and V(X) respectively, what would the mean and variance of cX be in terms of E(X) and V(X) if c is a constant
A 10 m diameter particle of unit density falls through air starting from rest. calculate the time required for the particle to attain 70% of the final terminal speed and the distance traveled by the particle during the time.
What relationship between Atterberg limits and cohesion for Shear test
An elevator weigh 4000kg. When the upward tension in the supporting cable is 48000N what is the upward acceleration Starting from rest, how far does it rise in 3s
How much money should an environmental soil cleaning company borrow to finance a site reclamation project if it expects revenue of $140,000 in the first year increasing by 3% per year over the 5-year cleanup period? The interest rate is 8%.
