When I looked at the calculation again after your input and substituted values I realized that the actual length of the lorry was 9.6m. The distance from the pivot to the ram was calculated as 9.6m -1.2m to get 8.4m.
Thank you Delphi51 for your time, and patience. Much appreciated.
Thank you again Delphi51.
So, if the ram limit is 45 tonnes, tipper length is 9.6m
The value for F would be 45000kg x 10 = 450KN
W is the load to be found
a = distance from pivot to load = 4.8 +3.6m = 8.4m
b = distance from pivot to centre of mass = 4.8m - 1.2m =3.6m
Substituting...
Thank you for your response Delphi51.
This is a real application that I have not perhaps explained fully. The ram lifting a tipper that is loaded fails causing the ram to fall back to the chassis, along with the tipper bed. The loaded tipper then bounces off the chassis onto the floor...
Please help with this query to find how much load a dumper truck can lift without it becoming unstable and toppling.
Homework Statement
A lorry has a volume of 42 cubic metres and can hold 78,000kg sand. The overall length of the vehicle is 9.5m with a pivot 1.2m from an end.
