The A36 steel bar AB has a square cross section. If it is pin-connected at its ends, determine the maximum allowable load P that can be applied to the truss. Use a safety factor with respect to buckling of 2.
air at one atmospheric pressure and at 20degc flows across a 12 mm diameter sphere witha free stream velocity of 5 ms.
determine the width w of the link bc needed so that the structure with load p 20 kips has a factor of safety equal to
a 0.2m3 rigid tank equipped with a pressure regulator contains steam at 2 mpa and 300 degrees c. the steam in the tank
If the flow rate of the water is to be maintained at 3.15*10-3 m3/s and the water temperature remains constant at 16oc ,estimate the power rating of the motor required to drive the pump.
The optical encoder emits 100 pulses per revolution. To execute a certain programmed instruction, the table must move from point (x = 25.0 mm, y = 28.0) to point (x = 155.0 mm, y = 275.0 mm) in a straight-line trajectory at a feed rate = 200 mm/mi..
Air enters the evaporator section of an air-conditioner at 100 kPa, 27oC with a volumetric flow rate of 6 m3 /min. R-134a enters the evaporator at 120 kPa with a quality of 0.3 and rate of 2 kg/min and it leaves as a saturated vapor at the same press..
air as an ideal gas with cp 0.241 btulbr is compressed from a state where the pressure is 3 atm and the temperature is
A car having a mass of 5500 kg is pulled slowly up a steep inclined track by a steel cable (see figure). The cable has an effective cross-sectional area of 320 mm2, and the angle of the incline is 310.
the position of a point p on a line is given by the equation x t sinpi t2. the point starts moving at t0. find the
1. calculate the specific volume of carbon dioxide 10 degrees celsius and 80 quality?2. calculate the specific volume
Why does the definition of NPSH include the dynamic head of the fluid? Isn't cavitation based only on the difference between the static head and the local vapor pressure?
refrigerant 134a is compressed with no heat transfer in a piston- cylinder assembly from 30 lbfin2 20 degrees f to 160
