The total load on the axle is 100 tonnes when the truck is loaded and 50 tonnes when the truck is empty. The average load on the axle is 75 tonnes which is 37.5 tonnes per tyre. If the average speed of the truck is 20kmh, the tyre rating would need to be 37.520 or 750 TKPH in order to not be a limiting factor.
Machines is approximately 2.4 x 3.6 meters or a total of 8.64 square meters. Assuming that the entire base is available and there are no leveling pads then the force exerted on the floor is 125KNewtons assuming that the weigh not given in metric tonnes so the total force imposed by the machine when not working is approximately 14.4 kNm2.
Examples of machine rates for a power saw, a tractor, a team of oxen, and a truck are in the following tables. Although the machine rates in Tables 3.5 to 3.8 share the same general format, there is flexibility to represent costs that are specific to the machine type, particularly in the calculation

Then its capacity considered is 1x100.04125 242.4242 m 3 day. That means, a hydraulic excavator can excavate 242.4242 m 3 of soil in one day. Its cost per day including driver and fuel is Rs. 5000. Then the cost of 10m 3 of excavation can be calculated as No. of days required for 10m 3 excavation 10242.4242 0.04125 days.
