Question:
Five annual deposits in the amounts of $1,200, $1,000, $800, $600, and $400 are made into a fund that pays interest at a rate of 9% compounded annually.
Determine the amount in the fund immediately after the fifth deposit.
4. Determine the values for the Energy Grade Line and the Hydraulic Grade Line for the tank and pipe system of problem 3. Plot the EGL and HGL.
The atomic-force microscope probe shown in Fig. 29.31 has a stainless steel cantilever that is 450 μ m × 40 μ m × 2 μ m. Using equations from solid mechanics, estimate the stiffness of the cantilever, and the force required to deflect the end of t..
A hortizonal rectangular concerte channel terminates in a free outfall. The channel is 4 m wide and carries a discharge of waterr of 12 cubic meters per second. What is the water depth 300 m upstream from the outfall?
A foundry form box with 25 kg of 200?C hot sand is dumped into a bucket with 50 L water at 15?C. Assuming no heat transfer with the surroundings and no boiling away of liquid water, calculate the net entropy change for the mass.
A contaminant in water is traveling through a saturated clay layer under a hydraulic gradient of 0.15. The clay has a hydraulic conductivity of 2 x 10^(-7) cm/s, a moisture content of 19%, and a Gs of 2.65.
A 900-mm strip of steel is bent into a full circle by two couples applied. Determine (a) the maximum thickness t of the strip if the allowable stress of the steel is 420 MPa, (b) the corresponding moment M of the couples.
Briefly explain how each of the following influences the tensile or yield strength of a semicrystalline polymer and why: (a) Molecular weight (b) Degree of crystallinity (c) Deformation by drawing (d) Annealing of an undeformed material
Determine the horizontal component of reaction that the pin A exerts on the two-member frame. Set F = 500 (Find Ax) Determine the vertical component of reaction that the pin A exerts on the two-member frame.
Assume the stress is uniform within the sample (the stress tensor is the same at every point), and therefore the only stress is normal in the direction of the force. What's Young's modulus for this material?
A hortizonal rectangular concerte channel terminates in a free outfall. The channel is 4 m wide and carries a discharge of waterr of 12 cubic meters per second.
A liquid has the peculiar property that its mass density increases linearly with depth according to the expression p = p_water (1+0.01d) where d is the depth below the liquid surface in meters. At a depth of 10 m, what is the gage pressure?
A lagoon with volume 1200 m^3 has been receiving a steady flow of a conservative waste at a rate of 100m^3/day for a long enough time to assume that steady-state conditions apply
