Deterine the approximate values of bar force in the members of thetruss in Figure for the following two cases.
(a) Diagonal bars are slender and can carry only tension.
(b) Diagonal bars do not buckle and may carry either tension or compression
an engineer measures the diameter of 20 tubes selected at random from a large shipment. the sample yields a sample mean
air is expanded from 2000 kpa and 500c to 100kpa and 50c. assuming constant specific heats determine the change in
1) An electron is shot through a magnetic field (see above) with an initial velocity of 100 ft/sec. The magnetic fieldaccelerates it in the perpendicular (normal) direction with a constant acceleration of 1000 ft/sec2. If the magnetic field has a d..
the duct between the turbine and the exit nozzle of a motor is 0.6 m diameter. the gas has a stagnant pressure and
Two torsional springs, M = ku, are used to assist in opening and closing the hood of this truck. Assuming the springs are uncoiled (u = 0°) when the hood is opened, determine the stiffness k (N # m>rad) of each spring so that the hood ..

air at 15 ? c ?ows over a ?at plate. a heater strip 10 cm long is placed on the plate at a distance 15 cm from the
q1. 1.5 kg of oxygen n2 and 0.15 kg of helium he2 are separated by a partition in a vessel.nbsp the nitrogen is at 5
One easy way to measure diffusion coefficients is the diaphragm cell shown in Fig. 2.2-4. These cells consist of two well-stirred volumes separated by a thin porous barrier or diaphragm. In the more accurate experiments, the diaphragm is often a sint..
