An arbor press is used to apply force to the workpiece at point C. The length h of handle DE can be adjusted by sliding it through a hole in shaft F such that 50 mm ≤ h ≤ 250 mm. The press has weight W = 350 N and simply rests on the rough surface of a table. Force P is applied perpendicular to the handle.
(a) If the handle is horizontal (a = 0°), determine the smallest force P that will cause the press to tip about point A.
(b) For any possible position of the handle, determine the smallest force P and the corresponding value of a that will cause the press to tip about point A.
