Greg · Answer 1 · 2022-10-21T17:58:34+0000

The correct choice is (c) 532 N

Best explanation: Pcos φ = F

∴ Force acting along the line of action,

P = F/cos φ

= 500/cos20°

= 532 N.

If the pressure angle of the rack is 20°, then force acting along the line of action between the rack and the gear teeth is
