m = Figure Q4 shows a Mach trim system from a 737-800. It consists of a hydraulic motor driving gear A which drives gear B. Gear B is directly connected to the horizontal stabiliser via rack and pinion as depicted below. Gear A has a mass of = 0.1235m and an angular acceleration of 6kg, a radius of gyration of KGA Ö = 0.2t rad/s². Gear B has a mass of m = 20kg, and a radius of gyration of 0.5341m. If the system starts from rest, determine the following when t = 3s: a) The velocity of the gear rack. KGb b) The distance the rack has travelled. c) If there is a contact force between the rack and gear B of 50N, determine the contact force between Gear A and B. d) The applied torque from the hydraulic motor.

Transcribed Image Text:Figure Q4 shows a Mach trim system from a 737-800. It consists of a hydraulic
motor driving gear A which drives gear B. Gear B is directly connected to the
horizontal stabiliser via rack and pinion as depicted below. Gear A has a mass of
6kg, a radius of gyration of KGA = 0.1235m and an angular acceleration of
20kg, and a radius of gyration of
Ö = 0.2t rad/s². Gear B has a mass of m =
m =
= 0.5341m. If the system starts from rest, determine the following when t = 3s:
KGb
a) The velocity of the gear rack.
b) The distance the rack has travelled.
c) If there is a contact force between the rack and gear B of 50N, determine
the contact force between Gear A and B.
d) The applied torque from the hydraulic motor.
