During an engine test on the ground, a propeller thrust $T=3140N$ is generated on the $2020-$kg airplane with mass center at G $.$ The

main wheels at B are locked and do not skid; the small tail wheel at A has no brake. Compute the percent change $n$ in the normal forces

at A and $B$ compared with their "engine$-$off" values.

Answers:
