A projectile is ejected into an experimental fluid at time t = 0 The initial speed is v0 and the angle to the horizontal is θ. The drag on the projectile results in an acceleration term aD = - ky where k is a constant and v is the velocity of the projectile. Determine the x- and y-components of both the velocity and displacement as functions of time. What is the terminal velocity? Include the effects of gravitational acceleration.
what is the maximum weight of the crate that the system can support? What is the angle theta required for equilibrium?
Where: Q is the amount of energy added (joules) M is the mass of the fluid (kg) C (subscript p) is the heat capacity of the fluid (joules/kg/K), and Delta T is the change in temperature (K or C degrees) A garage (24 ft x 24 ft x 10 ft) is illuminated..
What is the equation for average vehicle delay Is it averge queue over arrivals Average queue over average arrivals
A horizontal pre-stressing force of 500kN is applied to rectangler beam. the beam has a depth of 500mm and a width of 250mm. the force is applied at a distance of 80mm below the x-x axis.
Critical to facilitate economic development and jobs growth in the Central Bedfordshire area. This section of the route often experiences traffic congestion -
A short reinforced concrete column is subjected to a 1000 kN axial compressive load. The moduli of elasticity of plain concrete and steel are 25 GPa and 207 GPa, respectively, and the cross-sectional area of steel is 2% of that of the reinforced conc..
Plot a curve showing the relationship of Se versus L/r for steel columns. Draw the curve for slenderness ratios that vary from 0 to 200. Assume the proportional limit = 235 MPa
Find the components of the distance from the given axes to the centroid of the shaded area.
A rectangular concrete channel 10 m wide has a bed slope of 1 m/km and surface roughness equivalent to a Manning n of 0.02. It is proposed to use a hump on the channel bed for the purpose of flow measurement. If the maximum discharge is 150 m3/s:
Water at 68 degrees f is in a long, rigid cylinder of inside diameter 0.600 in. A plunger applies pressure to the water. If, with zero force, the initial length of the water column is 25.00 in, what will it's length be if a force of 420lbs is applied..
If the BOD5 of the river below the mill outfall must not exceed 5 mg/L, what percent removal of organic matter (BOD5) is required by the mill to meet this requirement?
The elastic ball bounces down a flight of rigid stairs. Determine the height h of the steps if all the trajectories between successive steps are identical. Use e = 0.85 and the initial velocity 6 m/s.neglect friction. (Theta=70 degrees)
