A projectile is fired into a block of wood that is hanging on the end of a light rigid rod. How you would estimate the speed of the projectile? What might account for the errors in your estimation?
The guy wires AB and AC are attached to the top of the transmission tower. The tension in cable AB is 8.6 kN. Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A.
A 1.5 meter deep vertical wall trench is to be cut in a soil whose unit weight is 17.36 kN/cubic meters, angle of internal friction is 25 degrees, and cohesion is 20.6 kN/square meters.
A 2.45 m wide rectangular channel has a bed slope of 0.0004 and Manning's roughness coefficient n of 0.015. For a discharge of 2.83 m^3/s, determine the type of water surface profile for depths of 1.52 m, 0.61 m, 0.30 m.
A 0.20 kg stone attached to a 0.8 m long string is rotated in a horizontal plane. The string makes an angle of 25° with the horizontal. Determine the speed of the stone.
Calculate average figures for tonnes/round and powder factors in kg/tonne and Determine the drill metres required to achieve a production rate from grade control blasting.
After removal from the oven, its unit weight is 109 lb/ft3. Compute the void ratio, porosity, initial moisture content, and a specific gravity of the soil, assuming its volume did not change during the drying process.
A person of dubious technical ability tells you that two of the direction angles for a particular vector are 30 and 40 degrees. If these direction angles are feasible, then determine the possible values for the remaning direction angle.
The variable capacitor in the tuner of an AM radio has a capacitance of 135pF. When the radio is tuned to a station at 550kHz what is the capacitance for station at 1600kHz.
Your response should be a minimum of one (1) single spaced page to a maximum of two (2) pages in length. Explain the process for establishing a centerline for a roadway for an existing road.
A fully penetrating well of 30 cm diameter in an unconfined aquifer of saturated thickness 50 m was found to give the following draw down - discharge relationship under equillibium condition.
The mass of each pulley of the system is 50 kg, and mass of the suspended object A is 160 kg. Determine the force necessary for the system to be in equilibrium? Be sure to draw complete free body diagram(s) for full credit.
In New york you had a balloon inflated with helium (He) and you measured its temperature, which was 89.6 degree F, and its pressure, which was 100,000 N/m^2. In Colorado, however, you noticed that the temperature of the He was 69.8 degree F and th..
