What are the forces on an aeroplane during take off Please be specific.?

Answer 1

The forces on an aeroplane during take off.Firstly the pilot opens the throttle and the aircraft gradually begins to accelerate,meaning that the thrust force generated by the reaction of the exhaust gases overcomes the resisting drag force simultenousely with the two pressure systems on the aerofoil shaped wings{low pressure-above the aerofoil and relatively high pressure below the aerofoil}the two pressures increase inversely to each other thus when the pilot knows he has enough airspeeds {knots}he pulls on his 'yoke'{control column}the flaps swivel downwards inversely to the elevator 'flap panels' on the horizontal stabiliser surface which are on the aircrafts tail-plane.From Newton's third law of motion it states that 'FOR EVERY ACTION THERE IS AN EQUAL BUT OPPOSITE REACTION' with these flaps deflected into the 'wind' there is an increase in the pressure below the wing and a decrease in the pressure above the wing due to the angle of attack of the flaps.Due to this principle any amount of degree moved of the 'flap' the action of the wing deflecting the in coming air downwards{due to the aircraft's acceleration} the wing thus the aircraft receive a reaction generated by the deflecting of the in coming air which has direction and magnitude {vector quantity}.In simple terms the wing gets sucked from above and pushed from below.If this force generated by the action of the wing is greater than the opposing force which in the whole aircrafts total weight the resultant is a force called LIFT, the aircraft archieves additional acceleration due to reduced drag caused by ROLLING RESISTANCE by the wheels just to name a few when the landing gear in nolonger in contact with the runway.
