What two driveshaft angle configurations does this diagram show?

It shows "Compensating Angles" (one U-joint 3° down, the other 3° up) and "Equal Opposing Angles," described as the Broken Back or "W" configuration (both U-joints 3° down).

What angle values are used in the examples?

Both configurations use 3° joint angles: 3° down and 3° up for the compensating layout, and 3° down at both ends for the broken-back "W" layout.

How do the force directions differ between the two configurations?

In the compensating-angle layout, the FORCE arrows at both ends point in the same direction, while in the equal opposing angle (broken back "W") layout, the FORCE arrows oppose each other.

What do the secondary views in each panel represent?

They show the same driveshaft and U-joints rotated 90°, illustrating the joint alignment from a second viewing plane.

This document is a technical schematic illustrating two common driveshaft universal joint (U-joint) working-angle configurations. The top panel, labeled "Compensating Angles," shows a driveshaft with one U-joint angled 3° down and the opposite U-joint angled 3° up (parallel yokes), with green FORCE arrows pointing in the same directions at both ends, plus side views showing the driveshaft rotated 90°. The bottom panel, labeled "Equal Opposing Angles (Broken Back: 'W' configuration)," shows both U-joints angled 3° down, with red FORCE arrows indicating forces that oppose or converge, again accompanied by views of the driveshaft rotated 90°. Red dashed centerlines through each yoke illustrate the angular relationship of the joint axes in each layout. A reader can learn how the two acceptable driveshaft geometry setups differ: in the compensating (parallel) arrangement the equal-and-opposite 3° angles cancel each other's velocity fluctuations with forces acting in the same direction, while in the broken-back "W" arrangement equal opposing 3° angles also cancel but produce opposing force directions. The drawings show yoke and U-joint cross details in both plan and 90°-rotated orientations, making this a general drivetrain geometry reference rather than a vehicle-specific document.
