A cylinder is internally pressurized to a pressure of 100 MPa. This causes tangential and axial stresses in the outer surface of 400 and 200 MPa, respectively. Make a Mohr circle representation of the stresses in the outer surface. What maximum shear stress is experienced by the outer surface?
Carbon dioxide enters an adiabatic compressor at 100kPa and 300K at a rate of 0.5kg/s and exits at 600kPa and 450K. Considering constant specific heat, determine (a) isentropic efficiency of the compressor (b) the rate of entropy change in (kW/K) ..
Disk A has a mass of 5 kg and disk B has a mass of 6 kg. They have the initial velocities shown in the figure. The coefficient of restitution between the disks is e = 0.4.
a 10 cm long circular pin kfin20 wmtimesk of 12-mm dia removes 53watts of heat from a hot base when the average
How many times more ignition energy is required to achieve ignition of a fuel-air mixture at sea level with T = 298 K than at altitude of 6000 m where pressure P = 47,166 Pa and T = 248 K?
Derive lift and drag coefficients based on empirical aircraft performance data.
Design a discrete (Z-domain) proportional plus integral plus derivatives (PID) controller for the type-1 plant derived from Lab 2. The controller should satisfy the following specifications:
ten kilograms of water at saturated liquid phase fills in a piston-cylinder device volume can change at 50oc. the
A hydraulic jump at the base of a spillway of a dam is such that the depths upstream and downstream of the jump are 0.90 and 3.6 m, respectively (see Video V10.11). If the spillway is 10 m wide, what is the flowrate over the spillway?
In a four bar mechanism ABCD, AD is fixed and is 150 mm long. The crank AB is 40 mm long and rotates at 120 rpm clockwise, while the link CD = 80 mm oscillates about D. Link BC and AD are of equal length. Using the analytical/mathematical solution me..
An outside wall of a building is constructed of 1/2 inch gypsum sheeting, 8 inches of concrete block (hollow, 3 oval core), and 4 inches of common brick. The inside of the building is maintained at 75F dry-bulb temperature and 65F wet-bulb temperatur..
Referring to Figure 2.21, prove Equation 2.48 for the angle of incidence. (Hint: use direction cosines of the sun-ray vector and a vector normal to the tilted surface to find the angle between them. The dot product of two unit vectors gives the co..
