A 70 Lb Thin Panel Is Placed In An Aircraft At An Angle Of 60 During Landing End A Sits On The Rough Horizontal Surface 1 (73.9 KiB) Viewed 27 times

A 70 lb thin panel is placed in an aircraft at an angle of 60 during landing. End A sits on the rough horizontal surface with an unknown frictional coefficient and end B sits on a smooth horizontal surface with a negligible frictional coefficient. The panel has length 10 ft and the deceleration of the plane is 14 ft/s²2. Determine the reactions at endpoints A and B as well as the minimum frictional coefficient to maintain equilibrium. The normal force at A is (put units in second box). The normal force at B is (put units in second box). The static coefficient necessary to maintain equilibrium is The reaction at A is (units) with an angle of degrees,
