An aircraft has a gross weight of 140000lb, wing area 2.333ft², maximum thrust 37800lb, CDo = 0.018, K = 0.048, MDR = 0.8, CL,max = 2.0. Plot the drag to weight ratio, D/W, and the maximum thrust to weight ratio, T/W, in the same figure as a function of true airspeed in mph (0- 400mph). Please show the equations used to model the T/W and D/W curves

Engineering drawing Find, top section, side section and front section?

The horizontal position of the 500-kg rectangular block of concrete is adjusted by the wedge under the action of the force P. Let the angle of the wedge be an arbitrary value 0 instead of the 5 degrees shown in the picture below. Let μ₁ be the coefficient of static friction between the wedge and the rectangular block, also let µ₁ be the coefficient of static friction between the wedge and the left wall. Finally let µ₂ be the coefficient of friction between the rectangular block and the horizontal ground surface. (a) Find the least amount of force required Pmin to move the block. Express your answer in terms of the angle 0, μ₁ and μ₂.
