A gearbox operating under steady state conditions recieves 24 hp along the input shaft and delivers 10hp along the output shaft. The outer surface of the gearbox is at 110F and has an area of 1.4 ft^2. The temperature of the surroundings away from the immediate vicinity of the gearbox is 70 F. For the gear box, determine a) the
A diesel engine has air before compression at 280 K and 85 Kpa. The highest temperature is 2219 K and the highest pressure is 6 MPa. Find the volumetric compression ratio and the mean effective pressure using cold air properties at 300K.
How can be determined the dynamic parameters of a second order system, wiht an Inertia (M), a dampening coeficient ( C ) and a Stiffness constant ( K).
Elaborate a Matlab model for this, using an non reinforced second order equation. M*d2y/dt2 + C * dy/dt + K* y =0
Need to obtain a working mathematical model of the balance beam problem, preferably with a cart, not a ball. i.e. Newtons laws leading through to equations of motion, aswell as transfer functions for use in matlab, any help will be much appreciated, thank you...
A box beam made from an extruded aluminium ally having 5 414 mm wall thickness is loaded by an inclined force P=100 N, as shown in the figure. Determine the maximum stress on section a-b. For the box beam, use the centreline dimension for finding I. (Note that the stress is far away from the support where large local stress co
Simply supported (in 3 dimensions) wooden beam under constant load at an angle - find stresses and locate Neutral Axis
A 150  200 mm wooden beam shown in Fig 9-4 (a) is used to support a uniformly distributed load of 4 kN (total) on a simple span of 6000 mm. The applied load acts in a plane making an angle, , of 20 with the vertical, as shown in Fig 9-4 (b) and again in Fig. 9-4 (c). Calculate the maximum bending stress
(a) Design a hollow steel shaft to transmit 300 hp at 75 rpm without exceeding a shear tress of 8000 psi. Use 1.2:1 as the ratio of the outside diameter to the inside diameter. (b) What solid shaft could be used instead?
