If the coordinate direction angles for F3 are a=120degrees, b=45degrees, y=60degrees, determine the magnitude and coordinate direction angles of the resultant force acting on the eyebolt.
Consider an air bubble rising from the bottom of a lake. Neglecting surface tension, determine approximately what the ratio of the density of the air in the bubble will be at a depth of 34ft to its density at a depth of 8 ft
A floor system consists of wide flange steel beams (W18 x 60) equally spaced at 8ft center to center. A 6inch reinforced concrete slab spans between beams. The bottom of the slab is coated with plaster and the top of the slab has ¾inch hardwood fl..
A -2.8% grade line meets a +3.6% grade line at station 125+00 at elevation of 1631.04. Assuming a length of curve is 650feet, compute the elevation and station of the BVC (PVC) and the EVC (PVT).
CE 3303 – Solids – MWF – Spring 2014 - Homework Set 23, – The pipe shaft of the auger, rotating at a constant angular velocity, is subject to the axial force and torque shown. Determine the stress state at points A & B and show on a stress element.
A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in.
A cast iron water main 14m long of 600 mm inside diameter and 30 mm wall thickness runs full of water and is supported at its ends. Calculate the maximum stress in the metal if density of cast iron is 7200 kg/m and that of water is 1000 kgm.
an embankment for a highway 30m wide & 1.5m in a compacted thickness is to be constructed from a sandy trucked from a borrow pit.
A simply supported steel 'I beam' is made of three 1"*8" plates with a mass of 898.4 lbmass each as shown in I beam form. Steel has a modulus of elasticity of 30*10^6 psi. The beam is allowed to deflect 1.05 inch.
The bar under the applied force is now 2.448 meters long. Calculate the following for the bar: a) engineering stress, b) engineering strain, c) true strain, d) Young's modulus, e) What additional information would you need to calculate the true st..
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
On average each student produces 1 kg of carbon dioxide per day. The recommended ventilation rate of fresh air to avoid excessive carbon dioxide buildup is 8 L per second per student.
Water flows through the pipe contraction shown. for the given 0.2 m difference in the meter level, determine the flowrate as a function of the diameter of the small pipe, D.
