9. Torque Conversion Graphs
Use Figure 1 for conversion of torque values Nm - ft.lb. Use Figure 2 for conversion of Nm - in.lb.

Figure 1: Nm - ft.lb
Find the Nm value on the horizontal axis. Move vertically to the solid black diagonal line. Then move horizontally to the vertical axis. Read the value in ft.lb.
Example: To convert 24 Nm to ft.lb., find 24 Nm on the horizontal axis (see the dashed line). Follow the dashed line vertically to the solid black diagonal line. Then follow the dashed line horizontally to the vertical axis. Read the value of 17.7 ft.lb.

Find the Nm value on the horizontal axis. Move vertically to the solid black diagonal line. Then move horizontally to the vertical axis. Read the value in in.lb.
Example: To convert 4.4 Nm to in.lb, find 4.4 Nm on the horizontal axis (see the dashed line). Follow the dashed line vertically to the solid black diagonal line. Then follow the dashed line horizontally to the vertical axis. Read the value of 39 in.lb.

GENERAL DESCRIPTION OF THE AIRPLANE
1. General
Diamond Aircraft Industries GmbH, N. A. Otto-Stra.e 5, A-2700 Wiener Neustadt, Austria, make the DA 40 airplane.
2. Description
The DA 40 is a single-engine, four seat, low-wing monoplane. It has a cantilever wing and a ‘T’ tail.
The airplane structure is fiber-reinforced plastic composite. This gives a very strong but light structure.

The semi-monocoque fuselage is a glass-fiber reinforced-plastic (GFRP) shell with GFRP bulkheads and stiffeners. Uni-directional carbon fiber bands give extra strength and stiffness in many areas. Left and right half-shells bond together with a center section to make the fuselage. The center section makes the bottom of the cockpit. It has the main bulkheads which connect to the spars in each wing. The vertical stabilizer has two GFRP half-shells that are part of the fuselage shells. 中國(guó)航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：鉆石40飛機(jī)維護(hù)手冊(cè) DA 40 SERIES AMM 1(28)
