An elastic foundation is often used to support heavy machinery that vibrates in such a way to cause problems for the rest of the structure. An elastic foundation with two equal springs each of stiffness k = 600 lbs/in is used to support the equipment of weight W = 1000 lbs shown. The equipment vibrates in such a way that it causes a vertical forcing function P(t) = 100 sin(20t) [lbs]. %3D (a) Draw the degree of freedom for the motion of the machinery. (b) Determine the equation of motion. What type of motion is this? (c) Determine the natural frequency and the displacement of the machinery. (d) What is the maximum amount of force that will be felt by the rest of the structure? (Think about what causes force to the rest of the structure) Rest of structure Hww
In an expansion phase for an existing system Engineers determined that they need Q=1.20 [m^3/s] of flow from Reservoir_A to Reservoir_B. Surface Water level at "A" 55.0 [m]; Surface Water level at "B" 80.0 [m]. PipeLine_length: 1500 [m], Desired Discharge = 1.20 [m^3/s]; Darcy-Weisb fric fact = 0.015 Min losses: K_inlet = 0.5 K_valve = 5.5 K_bend = 0.3 K_exit = 1.0 Pump charact.: see below. You are allowed 1) to add a second pump (same characteristics) 2) to adjust the System Curve: H_syst=H_static + H_dynamic all other parameters remain the same, i.e. length of pipe, roughness coefficient, minor loss coefficients.

Hab. Tiruneh, [4/2/2023 1:23 AM]A solar flux q ^ * falls on a unit length of a very thin tube of diameter d. Inside the tube is a stationary water with initial temperature T_{i} (same as ambient and no gradient inside at any time) and absorbs some of the heat while the rest leaves by convection from the surface to the ambient at T_{m} Develop an equation that can help to determine the temperature of the water at any time. Plot the temperature of the water against time. For a long elapsed time what will be the temperature? To simplify the analysis use theta = T*T_{e} * d*theta = dT theta_{i} = T_{i}*T_{o} (initial condition. Hab. Tiruneh, [4/2/2023 11:53 AM]A flat wall is exposed to an environmental temperature of 38°C. The wall is covered with a layer of insulation 2.5 cm thick whose thermal conductivity is 1.4W / (m ^2 *` C and the temperature of the wall on the inside of the insulation is 315°C. The wall loses heat to the environment by convection. Compute the value of the convection…
The Antoine Equation can be used to estimate vapor pressure at various temperatures for different substances using sets of empirically-derived constants. The equation can be written as: Where for water A = 8.07131, B = 1730.63, C = 233.426, T = temperature [°C], and P = vapor pressure [mmHg]. Note that with these constants the temperature and pressure must be provided in °C and mmHg, respectively. Using the Antoine Equation and the provided constants, what atmospheric pressure (provided in terms of % of standard atmospheric pressure) will permit water to boil at 75 °C?

A cylindrical buoy weighing 20 kN is floating in ocean. The buoy has a diameter of 2 m and height 2.5 m. Can the buoy float with its axis vertical? If now, a chain may be tied at the bottom of the buoy and anchored, what is the tension required in the anchor chain to make the buoy stable? Take sp. gravity of sea water = 1.025. [Ans. 12.9 kN]
conduct a full kinematic analysis and calculate dynamic reaction forces in a linkage mechanism, calculate instantaneous torque, required to drive the mechanism 470 Figure 1. Left: An operating pumpjack linkage mechanism. D G E A Φ B B T H WOA Right: A mechanical Figure 1 shows a pumpjack operating at an oil well. Its representation as a linkage is also shown in Figure 1. The pumpjack is driven by a motor attached to crank OA. A constant torque T' is applied to the crank and the crank rotates at a constant angular velocity wOA. A force P is applied vertically downwards at the end of the walking beam BD, which has its centre of mass at point G. To design the mechanism, a careful kinematic analysis of the mechanism needs to be conducted. To avoid mechanical failure and to provide adequate support to the mechanism, the engineer needs to analyse the reaction forces in the joints. Masses of links OA and AB are assumed to be smaller in comparison with the mass of BD and are ignored in the…
