Question: An airplane weighing 100 kN is 24.4 m in span. Its tailplane, which has a symmetrical section and is located 15.2 m behind the center of pressure of the wing, is required to exert zero pitching moment at a speed of 67 ms-1. Estimate the required tail-setting angle assuming elliptic loading on the wings.
A model of a helicopter rotor has four blades, each 3.60 m in length from the central shaft to the bladetip. What is the radial acceleration of the blade tipexpressed as a multiple of the acceleration due to gravity,g?
A portion of a soap bubble appears yellow (λ = 588.0 nm in vacuum) when viewed at normal incidence in white light. Decide the two smallest, non-zero thicknesses for the soap film if its index of refraction is 1.40.
Consider the Point Source and Guard Ring configuration as shown in quadrant B of Fig. 1. If you apply 28V to the guard ring and 0V to the central point on the conductive paper- Where is the electric potential most positive?
On a frictionless horizontal air table, puck A (with mass 0.253kg ) is moving toward puck B (with mass 0.365kg), which is initially at rest. After the collision, puck A has velocity 0.115m/s to the left, and puck B has velocity 0.655m/s to the right...
