what are the properties of petrol that it makes particularly suitable for the use as afuel in a motor vehicle.
Fluid/Dam Pressure, Compare the pressure force exerted on the face of two dams that hold a fresh water of 1000 Kg/m^3 density and a salty water of 1030 Kg/m^3
Two forces are applied to the pipe AB as shown. Knowing that the pipe has inner and outer diameters equal to 35 mm and 42 mm, respectively, determine the normal and shearing stresses at (a) point a, and (b) point b
Sketch the fully annotated velocity triangles for a Parsons turbine stage. Use your sketch to show that the specific work produced per stage is given as w_stage = (C_b)^2 [1 + 2(f/C_b)(cot(B_1))].
Note that the positive y direction is downward and counterclockwise torques are positive. find alpha the angular acceleration?
Sketch the frequency response of the system. Overlay the frequency spectrum of the excitation and as you start the system up, increasing Ω from 0 to 60 rpm, what speeds are most likely to excite large amplitude response? Why?
With reference to basic constructional features, contrast the methods of compression employed by positive displacement and dynamic air compressors.
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. explain how these thermometers can be used to estimate the amount of water vapour in the air.
the traveling crane consists of a 5-m-long beam having a uniform mass per unit length of 20kg/m. The chain hoist and its supported load exert a force of 8 kN on the beam when x=2m. draw the shear and moment diagrams for the beam.
Assuming a small oscillation about the horizontal equilibrium position, determine position X for the slider such that the friction period is 1 second.
Find the velocity of the bullet and the distance it has traveled into the water after 4 seconds. Please show detailed step by step process to solution.
A short post AB has a commercially manufactured eyebolt screwed into its end. Three cables attahced to the eyebolt apply forces shown.
