Two forces acting on the ring of the force table these are: F1 = 0.200 N at angle 50° and F2 = 0.450 N at angle 130°, note that the angles are with
respect to the positive x-axis counterclockwise.
Using the analytical method,
method, determine the resultant force FR
(magnitude)

In a load, the load is paralel to the shaft. n a. angular n b. thrust n c radial n d. none of the above

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
