Problem 9.40 2. Problem XXXXXXXXXXlbf = 666 Newtons. Use metric units. Lift = weight for skydiver to ‘float’. 3. Problem 9.70 Convert given values to metric units, mph to m/s, ft2 to m2, ft to meters, etc. before calculating lift coefficients. 4. Problem 9.75 The increase in maximum tractive (downwards force) on the wheels = coefficient of friction x downwards (negative) lift force from spoiler. The airfoil shape used on the spoiler is never shown, but its lift coefficient is given. Convert given values to metric units, mph to m/s, ft2 to m2, ft to meters, etc. before calculating lift coefficients. 5. Problem 8.29
