1.102 Determine the intensity w of the maximum distributed load that can be supported by the hanger assembly so that an allowable shear stress of τallow = 13.5 ksi is not exceeded in the 0.40-in.-diameter bolts at A and B, and an allowable tensile stress of σallow = 22 ksi is not exceeded in the 0.5-in.-diameter rod AB
determine the velocity of the 30 kg block A if two block are released from rest and the 20 kg block B moves 0.6 m up the incline. the coefficient of kinetic friction between both blocks and the inclined plane is 0.10
A person of mass 80kg places all their weight on the pedal of a foot operated hydraulic jack. The diameter of the hydraulic cylinder under foot pedal is 4cm and the diameter of the jack cyclinder is 9cm (Assume g is 9.81 m/s^2)
A first order reaction takes place in a batch reactor to remove an undesired contaminant (compound A) from a drinking water. The rate constant = 2.0 per day. The initial concentration = 75mg/L.
when a force F acts on a linear spring, the elongation x of the spring is given by F=kx, where K is called the stiffness of the spring. Determine the dimension of K in terms of the base dimensions of an absolute system of units
a hollow rectangular masonry pier 600mm900mm and 150mm thick transmits a vertical load of 500knnbspin a vertical plane
A pendulum consists of a slender rod, AB, of weight Wr= 8.60 lb and a wooden sphere of weight Ws= 21.7 lb .(Figure 1) The length of the rod is d = 7.70 ft and the radius of the sphere is R = 0.500 ft .
When using singularity functions, if I have a reactionary moment at a cantilever connection, do I use the right hand rule to solve the moment and determine it's direction through the reactions
A .2kg mass of argon gas fills a .05m^3 piston-cylinder volume at a pressure of 400 kPa absolute. The piston induced pressure is changed until the volume expands to twice its original value, while the temperature remains constant.
An automobile having a mass of 900 kg initially moves along a level highway at 100 km/hr relative to the highway. It then climbs a hill whose crest is 50m above the level highway and parks at a rest area located there.
Find the length and width of a square basin for virus disinfection of a flow of 6 MGD. You may assume a depth of 5 ft, a C•t product of 10 (mg/L) •min for 1.5-log removal, and a target free chlorine residual of 0.6 mg/L.
The path of the airplane is described by the equation y=kx^2, where k=6 x 10^-4 m^-1. Provide the expression for the velocity and acceleration of the airplane when x=390m. Express the velocity in m/s and the acceleration in m/s^2.
