Recognize whether or not a force creates a moment about an axis based on its line of action

I just need an exemple

Design a combined footing for columns of 400×400 300 x300mm are carrying 1200 kN and 1000 kn and spaced 5m apart . . M25 fe415

I need ditto. answer, don't copy all answers are wrong..

A 455-mm diameter concrete pipe changes slope from 0.4% to 0.1% at a manhole. The roughness height of the pipe is 1.5 mm and the design maximum flow rate is 84.2L/s. The inflow and outflow pipes are located directly opposite each other. Determine the required drop at the manhole.

Please shows steps for atleast one iteration.

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.

The compressibility of water  is 4.4 x 10-10 Pa-1. The compressibility  for clay, gravel and granite are approximately 10-6, 10-8, and 10-10 Pa-1, respectively. What is the percentage of water released from storage due to decompression of the aquifer skeleton and due to decompression of water for a clay, gravel and granite confined aquifers? The porosities are 35%, 25%, and 1% for clay, gravel and granite aquifers, respectively. The aquifers have a similar thickness of 20 m and cover a land area that has a length of 80 km and width of 125 km. How much water will be released from each aquifer, in m3 and in km3, if the head in the aquifers dropped by 5 ft?

A present asset (defender) has a current market value of $85,000 (year 0 dollars). Estimated market values at the end of the next three years, expressed in year 0 dollars, are MV1= $73,000, MV2 = $60,000, MV3 = $40,000. The annual expenses (expressed in year 0 dollars) are $15,000 and are expected to increase at 4.5% per year. The before-tax nominal MARR is 15% per year. The best challenger has an economic life of five years and its associated EUAC is $39,100. Market values are expected to increase at the rate of inflation which is 3% per year. Based on this information and a before-tax analysis, what are the marginal costs of the defender each year and when should you plan to replace the defender with the challenger?
