Explanation Given information: The weight of the airplane is W . The wing span of the airplane is b . The constant velocity of the plane is v . Consider the diameter of the air cylinder is b . Consider the angle of deflection of the cylindrical stream is θ . Calculation: Consider the mass flow the stream is denoted by d m d t . The mass flow is steady as the velocity of the airplane is constant. Calculate the mass flow of the stream using the relation: d m d t = ρ v A (1) Here ρ is the mass density of the air, A is the cross-sectional area of the air cylinder. Show the cross-sectional area of the cylinder ( A ) as follows: A = π b 2 4 (2) Modify Equation (1) using Equation (2). d m d t = ρ v ( π b 2 4 ) Consider the velocity of the air stream in the vertical direction is denoted by v 2 , y . Calculate the velocity v 2 , y using the relation: v 2 , y = − v sin θ Consider the Equilibrium of the plane in the vertical direction. Equate the lift provided by the wings with the self-weight of the plane

The figure (below) shows a device for clearing debris using a jet of air discharged from a nozzle. As shown, the jet is striking a cube-shaped object (density 1900 kg/m³) sitting on the floor. Assume that in all cases that (i) the entire jet is deflected by the cube; and (ii) the cube slides rather than tumbles. Air jet If the jet diameter is 38 mm and the air velocity is 25 m/s, what is the heaviest cube that could be moved? What are the dimensions of the cube? If needed, assume the coefficient of friction is 0.60.

A spring of force constant K attached to the wall on a horizontal smooth plane. The spring is compressed by a block of mass 6 kg a distance x= 0.2 m. The speed of the block as it released and passes the equilibrium position is 5 m/s. Find the force constant k (in N/m). 100000000000 X=0

An aircraft, of mass 2000 kg, is following a circular path in the vertical plane as shown in Figure 2. When the flight path of the aircraft is at an angle of 30° from the horizontal, the aircraft's velocity is 150 m/sec, the radius of curvature of its trajectory is 1000 metres, and the net thrust (engine thrust minus drag) is T = 30 kN and acts along the flight path. Assume that the lift force L is perpendicular to the flight path. Draw a free-body diagram showing all forces acting on the aircraft. Calculate the resultant acceleration and its angle from the flight path. Also calculate the lift force L. r= 1000 metres 307 Figure 2
