The structure consists of two identical bars joined by a pin at B. Neglecting the weights of the bars, find the magnitude of the pin reaction at C.
A pin-connected truss is loaded and supported as shown. Each aluminum member has a cross-sectional area of A = 2.6 in.2. Assume a = 4.75 ft and b = 5.70 ft. If the normal stress in each member must not exceed 60 ksi, determine the maximum load Pma..
Assuming the ball experiences a downward acceleration of a = 10-9v2 when in the water, determine the velocity of the ball when it strikes the bottom of the lake.
What is the level of humidity in a building at the time installation of the interior wall finishes is completed? Why? What should be done about this and why?
The following data apply to a closed link traverse. Compute preliminary azimuths, adjust them. and calculate departures and latitudes, misclosures in departure and latitude, and traverse relative precision.
A 5 km2 lake does not have a defined input but receives runoff from its watershed (25 km2). The area receives 60 cm/yr in precipitation. Evaporation from the lake surface is 10 cm/yr with watershed evapotranspiration of 20 cm/yr.
You will be using a large crane... lets say one with a capacity of 30T. What considerations need to be made prior to picking up a 15T load with the crane? If you are familiar with the use of a crane be sure to include the discussion of the outriggers..
The object ABC consists of two slender rods welded together at point B. Rod AB has a mass of 1 kg and bar BC has a mass of 2 kg. Knowing the magnitude of the angular velocity of ABC
Calculate the expected rate of flow (in liters/sec) when the sand is clean Calculate the expected rate of flow (in liters/sec) when the sand needs to be backwashed.
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.
A tensile load of 50 000 lb is applied to a metal bar with a 0.6x0.6 in cross section and a gage length of 2 in. Under this load the bar elastically deforms so that the gae length increases to 2.007 in
Vehicles arrive at a tollbooth according to the function h(t)= 5.2-0.2t, where h(t)is in vehicles per minute and t is in minutes. The toll booth operator processes 3 vehicles per minute.
A 3 kg mass is attached to one end of a 1 m long cord. The other end of the cord is attached to the center of a rotating disk (with radius greater than 1 m) that has a very large constant angular velocity.
