A particle travels along a path defined by the parabola y=0.5x^2. If the component of velocity along the axis is Vx=6t with t in seconds. determine the particle's distance from the oriigin which is at t=3s. when t=0, x=0, and y=0. also determine the magnitude of acceleration when t=3, x and y are in ft.
For an unknown alloy the stress at which plastic deformation begins is 400MPa and the modulus of elasticity is 120GPa. If the original specimen length is 76 mm, what is the max length to which it may be stretched without causing plastic deformatio..
A short Reinforced Concrete column is 300mm x 400mm. It is required to carry an ultimate load of 1500kN and an ultimate major axis bending moment of 300kNm. Calculate the area of reinforcement required.
A water treatment plant is being designed for a flow of 1.6 m^3/s. How many rapid sand filters, using only sand as the medium, are needed for this plant if cross-sectional area of each filter is 10 m x 20 m
A paddle wheel, inserted inserted into the volume, does 720 KJ of work on the air. If the volume is 2 cubic meters, calculate the entropy increase assuming constant specific heats.
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
The 50mm radius pulley A of the clothes dryer rotates with an angular acceleration of (80^(1/2)A) rad/s, where angle A is in radians. Determine its angular acceleration when t= 2 , starting from rest.
The earth's interior comprises three principle regions: the Core (16.4% of the earth's total volume, density= 11.2 kg/L), the Mantle (82% fo the earth's total volume, density= 4.7 kg/L), and the crust (1.6% of the earth's volume, density equals 2...
At the end of 15 years, the first motor will have a salvage value of $50 and the second motor will have a salvage value of $100. consider the MARR to be 8%. (note : 1HP=0.7457 kw). Determine which motor should be installed based on the PW criterio..
A cylindrical specimen of a metal alloy is stressed in compression. if its original and final diameters are 40.00mm and 40.10mm respectively, and its final length is 120.00mm, compute its original length (L1) if the deformation is totally elastic.
Determine the horizontal reaction that is developed on the gate at C.
