1. The problem statement, all variables and given/known data A 1600kg jet engine is fastened to the fuselage of a passenger jet by just three bolts (this is the usual practice). Assume that each bolt supports one-third of the load. (b) During flight, the plane encounters turbulence, which suddenly imparts an upward vertical acceleration of 2.8 m/s2 to the plane. Calculate the force on each bolt now. 2. Relevant equations F = ma 3. The attempt at a solution The force acting on the engine is the sum of all forces acting on the engine because of Newton's second law. So first I found the force of gravity on the engine F=ma F=1600(9.8) F=15,680 N then I found the force the turbulence had on the engine F=1600(-2.8) F= -4480 N Then the sum of these forces is -4480 + 15,680 = 11,200 Then I divided this by 3, for the force on each bolt and got 3,733 N. But when I typed this answer in it was not correct and I do not know what I am doing wrong.
