The hook is subjected to the force of 80 lb. Determine the state of stress at point B at section a - a . The cross section has a diameter of 0.5 in. Use the curved-beam formula to compute the bending stress.
Saturated water vapor at 150 deg C is compressed in a reversible steady-flow device to 1000 kPa while its specific volume remains constant. Determine the specfic work required in kJ/kg. The heat transfer is not negligible.
An underwater instrument is modeled as shown in the figure. Determine the coordinates of the centroid of this composite volume
Calculate the specific surface of a cube (a) 10 mm, (a) 1 mm, (a) , and (d) 1 nm on a side. Calculate the specific surface in terms of areas
The forces F1, F2, and F3, all of which act on point A of the bracket, arespecified in three different ways. Determine the x and y scalar components of each of the three forces.
A rigid beam (AB), 12 feet in length, with a point load of 9 kips (4 feet from A) is resting on two short steel rods (AC & BD). Diameter of Rod AC is 1 inch, Rod BD diameter is 2 inches.
a thin walled circular tube and a solid circular bar of the same material are subjected to torsion. the tube and the bar have the same cross-sectional area and the same length.
A 1 L beaker contains a material that decays at a first order rate of 0.25/day. How long will it take for the concentration in the container to be reduced to 10 % of its originalvalue?
The maximum wind pressure on the traffic sign is 200 kg/m2. The maximum allowable shear stress is 350 kg/cm2. Design the traffic pole (only vertical element) against torsion knowing that angle of twist at the base should not exceed 6°.
what is the effect of temperature on compressive strength of concrete?
The portable floor crane in the automotive shop is lifting a 420 lb engine. For the position compute the magnitude of the force supported by the pin at C and the oil pressure p against the 2.70 in. diameter piston of the hydraulic cylinder unit AB..
plasticization on the dynamic mechanical properties (such as loss modulus). Also discuss the implications of such effects to fatigue deformation.
Problem: A 24F-V4 Douglas Fir-Larch glulam is used to span 32 ft, carrying an ASD load combination (D+S). The load is uniform over a simple span, and the beam is laterally supported so that lateral torsional buckling is prevented.
