Calculate the aerodynamic lift Land drag Dacting on the glider.Answers:L-D- The 205-kg glider Bis being towed by airplane A, which is flying horizontally with a constant speed of v- 202 km/h. The tow cable hasa length r-61m and may be assumed to form a straight line. The glider is gaining altitude and when e reaches 12, the angle isincreasing at the constant rate ở - 4 deg/s. At the same time the tension in the tow cable is 1135 N for this position. Calculate theaerodynamic lift Land drag D acacting on the glider.Assume o - 10°.

MIDSPAN DEFLECTION IN A SIMPLY SUPPORTED BEAM (Use the Moment Area Method technique discussed for this topic. Note that for every load in the span, partner it with a same load to make the beam symmetrically loaded. This process doubles the midspan deflection of the given original beam.)
