3.7 PRACTICE PROBLEMS
À p1. Crank CB is 6" in length. Find the location of point D as a function of the crank angle at B using either complex numbers or complex polar notation.
2. The test pilot of the aircraft below is doing loops to evaluate the cockpit cup holders. Part way through one loop he notices (apparently) another plane one mile straight ahead from his position. If he is flying upside down at the location shown below, what is the absolute position of the other plane relative to the control tower. Note: use proper notation to solve this problem.
