An existing building is suffering from cracks in the exterior walls. The investigating engineer wants to ensure that the foundat
ions are not overloaded. The existing columns carry dead live load of 45,000 pounds. The footings are 3 ft 6 in. x 3 ft 6 in. x 1 ft 6 in. thick and rest on sandy soil. The soils report estimates the allowable soil bearing pressure to be 2500 psf. What would be the smallest area for a safe footings are adequate to carry the load?
True strain and engineering strain? True stress is defined as the load divided by the cross-sectional area of the specimen at that instant and is a true indication of the internal pressures. ... Engineering stress is defined as the load divided by the initial cross-sectional area of the specimenAnswer:
Brake mean effective pressure is a method to calculate the engine cylinder pressure which would give the measured brake horsepower. Brake mean effective pressure is used to identify engine efficiency regardless of capacity or engine speed.
It is used to identify engine efficiency.It is measured by means of transducers or pressure gauges.
