[Bert2]

Sorry seem to have forgot how to calculate the reaction upon a three point beam, could someone point me in the right direction please... im am on the right path of quadratic equation given you have two unkowns?

please see attached.

thanks

My basis was downwards as positive, the front end lifts up so the negative implies opposite sense or upwards.

again, how does a tire react -ve load ? ...

it can't ... the three tires will compress under the load with a small change to react the moment, but all tires Must have +ve (= compression) reactions.
