### Excavator - Wikipedia

Jul 16, 2020 · So, the formula is: Ab = Wb * Lb, where Wb and Lb are the width and length of the bottom of the excavation. At = Wt * Lt, where Wt and Lt are the width and length of the top of the excavation. In our example, Wb = Lb = 5 and Wt = Lt = 15, so Ab = 5 * 5 = 25 and At = 15 * 15 = 225, and D = 5. Therefore, the volume is: = 542 cf or 20.0 cy.

### Ground pressure | Tractor & Construction Plant Wiki | Fandom

Ground pressure is the pressure exerted on the ground by the tires or tracks of a motorized vehicle, and is one measure of its potential mobility, especially over soft ground. Ground pressure is measured in pascals (Pa) which corresponds to the EES unit of pounds per square inch (psi). Average ground pressure can be calculated using the standard formula for average pressure: P = F/A. In an
