Consider a right-hand Cartesian coordinate system as shown in Figure. We have a wire along the x-axis carrying 12A in the positive x direction and a constant flux density of 0.3T directed in the positive z direction.
a. Determine the force and its direction on a 0.2m length of the wire.
b. Repeat if the field is directed in the positive x direction.
A pin-connected truss is loaded and supported as shown. Each aluminum member has a cross-sectional area of A = 2.6 in.2. Assume a = 4.75 ft and b = 5.70 ft. If the normal stress in each member must not exceed 60 ksi, determine the maximum load Pma..
A concrete cylinder of height 8 inches and diameter of 4 inches was tested in the lab. The maximum compressive force was found to be 150,000 lbs and a tensile force of 25000 lbs.
What is meant by the value of f, a, s on the fresh concrete mix is:A. The weight ratio of water to the weight of the cement mixture. B. The weight ratio of water to the weight of cement and aggregates. C. Factors dough with a water content ratio of t..
A short 60mm diameter circle bar is made of material for which the maximum safe compressive strees is 80 MPa and the maximum safe shearing strees is 30 MPa.
Assume the overall system is at steady-state, theflow rate is 15 L/min, the detention time is the PFR is 1.5 hours,and the decay rate of compound A is defined by a first-order ratereaction (k = 1 h-1).
A frictionless, incompressible steady flow field is given by V=2xyi-y^2j in arbitrary units. Let the density be ρ_0=constant and neglect gravity. Find an expression for the pressure gradient in the xdirection.
Water flows through a 75 mm constriction in a horizontal 150 mm pipe. If the pressure in the 150 mm section is 345 kPa and that in the constriction 207 kPa, calculate the velocity in the constriction and the flowrate.
A human with a surface area of 2 m^2 and a surface temperature of 27 degrees celcius radiates into a large room (which acts as a black body), the surfaces of which are at 15 degrees celcius.
The pipe has a flow of 5 m3/s. The stream's chloride concentration just upstream of the pipe's dischage is 12 mg/L, and the runoff pipe's discharge has a chloride concentration of 40 mg/L. Chloride is a conservative substance.
Simply answer the questions in bold below the problem description, No need tonumerically solve either problem. Give each force on your FBD(s) a unique label, but use the same label for identical forces.
A river is 6 m deep. The riverbed material has a saturated unit weight of 19.5kN/m3. What is the effective vertical stress 12 m below the water surface?
