The four forces acting on helicopter in forward flight are...? correct answers Thrust, drag, weight, lift Bernoulli's Principle or the "venturi effect" correct answers As air flows over upper surface of airfoil, camber (curvature) of airfoil causes increase in speed of airflow which decreased pressure. Pressure is increased on bottom and this gives lift. Newtons Third Law of Motion and how it applies to helicopters correct answers "for every action there is an equal and opposite reacti...

STRAIGHTERLINE PHYSICS 250 QUESTION SET STRAIGHTERLINE PHYSICS 250 QUESTION SET WITH GUARANTEED ACCURATE ANSWERS (EXAM 2) 0 ± 2% - Accurate AnswerYou attach a rope at an angle of 0 degrees above the horizontal to a 541 kg box. The coefficient of static friction between the block and surface is 0.32 and the coefficient of kinetic friction is 0.28. Assume you push just hard enough to break static friction and the box starts to move. Use that force to calculate the acceleration of the...
