Design a square spread footing for the following conditions: service dead load = 350 kips, service live load = 275 kips. soil density = 130 pcf (including the weight of the floor slab). allowable soil pressure = 4500 psf at 5 ft below the basement floor. assume an 18 in. by 18 in. interior column (f’c = 5000 psi). footing f’c = 3000 psi and fy = 60 ksi. place bottom of footing at 5ft below floor level. estimate floor thickness as 6 in. (hint: estimate thickness of 36 in.)

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
