Design forms for 13’-8” high wall to be concreted at the rate of 5 ft per hour, internally vibrated. Assume the mix is made with Type I cement, with no pozzolans or admixtures, and that the temperature of concrete at placing is 75°F. The unit weight of concrete is 150 pcf with a slump of 3.75 inches. The forms will be used only once, so short-term loading stresses will apply. Use form grade plywood sheathing 7/8 in. thick in 5×10-ft sheets, and 5,250-lb coil ties are on hand. Framing lumber of No. 2 Douglas Fir-Larch is to be purchased as required.

A body of water is being retained by a concrete dam wall (15 ft high and 6 ft thick). What is the maximum height the water can rise without causing the intensity of pressure at the toe greater than twice the average pressure on the base? Assume that concrete weighs 150 lbs per cubic foot, there is no seepage causing uplift against the bottom of the wall, and water weighs 62.5 lbs per cubic foot.

A 17-ft-high retaining wall is restrained from yielding. The shear strenght parameters are c = 0 and φ33 The water table being 7 ft below the surface. The saturated unit weights of the rock is 122 lb/ft³, above the water table the (dry) unit weight of the rock is 104 lb/ft³. Assume that for OCR= 2. Calculate the lateral force Po per unit length of the wall. Also, determine the location of the resultant force.

Determine the maximum allowable span of nominal 2x4 wall forms studs carrying a design load of 1000 psf. Stud spacing is 16” on center. Use the allowable stresses for Douglas Fir from Table 13-8 and 7 day load duration. Assume that studs are continuous over 3 or more spans. Limit deflection to l/360 of span length. Based on the maximum allowable span, check for crushing of studs on double 2x4 wales. Conditions are dry.

A supplier charges $11.99 per unit for bulk lots of proprietary 6 ft. high speed HDMI cables. Assuming: A profit margin of 8% and a cost markup pricing approach Direct material costs of $6.50 per unit Direct labor costs of $1.50 per unit An industry average of overhead costs of 200% of labor costs. Do you feel that the price per unit is fair, or do you need to apply pressure for a substantially lower price? Why? 2. A labor intensive product...
