Sketch a planar model of a K-MAX helicopter delivering cargo to a moving ship, as shown in Figure 8.28, using a point mass to represent the helicopter. Derive the inertial kinematics of the cargo with respect to a point fixed to the deck of the ship, assuming that the length of the cargo sling is fixed.
the 680 kg load suspended from the helicopter is in equilibrium. the aerodynamic drag force on the load is horizonal.
A high strength steel [E = 200 GPa] tube having an outside diameter of 80 mm and a wall thickness of 3 mm is bent into a circular curve having a 52 m radius of curvature. Determine the maximum bending stress developed in the tube
Capture the Rayleigh line between Mach number 0.2 to 4.0 initially by adding heat q in small increments taking the flow to M = 1 at location 2, there after removing heat until you achieve M = 4. Use the differential equations
Water at 20 C flows across a flat plate at a velocity of 0.25 m/s. compute the distance from the plate’s leading edge to where the laminar boundary layer thickness is 3 cm. Verfiy that the flow is indeed lamiar at this distance.
Briefly describe the three main types of software maintenance. Why is it sometimes difficult to distinguish between them?
a thin flat plate that is 0.2 m x 0.2 m on a side with rough top and bottom surfaces is placed in a wind tunnel so that
Consider a material composed of equal volumes having different yield strengths, YB = 1.5YA, but the same elastic moduli, EA = EB. Assume that during strain- ing both regions undergo the same strains (εA = εB ) and that there is no strain- hardening i..
a child of mass 20 kg is standing on a plank inclined at 20 degrees to the horizontal. how much force does the child
if blocks a and b of mass 10 kg and 6 kg respectively are placed on the inclined plane and released determine the force
a polymer component that needs to maintain a stress level above 10 mpa for proper functioning of an assembly is
Show transcribed image text The truss shown was designed to support the roof of a food market. For the given loading, determine the force in members FG, EG, and EH. Hint: Method of Section.
A simply supported wide-flange beam of span length L carries a vertical concentrated load P acting through the centroid C at the midpoint of the span (see figure). The beam is attached to supports inclined at an angle α to the horizontal.
