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.
The maximum flexural stress on a transverse cross section of a beam2" x 4" with a rectangular cross section must not exceed 8 ksi.Determine the maximum resisting moment Mr that the beamcan support if the neutral axis is
A 5 cm diameter, 6 m high pole is fixed in concrete. The pole supports a circular 4 m diameter sign. Estimate the maximum moment that must be resisted by the concrete for a wind speed of 30 m/s (wind is assumed normal to the sign; density of air = 1...
Explain briefly shallow foundation?
A stockpile of gravel that has a water content of 6% is rained on so that its water content increases to 9%. Compute the difference in the weights of dry gravel in a 10 ton truckload taken from the pile before and after the rain.
Due to temperature change, a 1/32" hole mismatching occurred. What is the pulling force, in lbs, to be applied for one of the plates to match the two holes The plate length is 3 ft (from the left end to the hole) and its cross section is 1/8" x 1"..
All the silt is saturated even after the water table is lowered. (In this problem, treat the unit weight above the water table as bulk unit weight and the unit weight below the water table as saturated unit weight.)
When fluid of specific weight 8.2 KN/m^3 flows in a 150-mm-diameter pipe, the frictional stress between the fluid and the pipe wall is 25 N/m^2. Calculate the friction head loss per meter of pipe
A plane truss has joint loads P, 2P, and 3P at joints D, C and B, respectively where load variable P=23kN. All members have two end plates which are pin-connected to gusset plates.
Structure O A B C is built in at point O and supports forces from two cables. Cable E A D passes through a frictionless ring at point A, and cable O C G passes through a frictionless ring at point C. If the force in cable E A D is 800 lb and the forc..
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?
Consider the pressure-driven flow between stationary parallel plates separated by distance 2b. Coordinate y is measured from the channel centerline. The velocity field is given by u=u max(1-(y/b)^2).
