Here are the translations of the Chinese terms related to levers: 1. 支点O: The fixed point around which the lever rotates. 2. 动力F1: The force that causes the rotation of the lever. 3. 阻力F2: The force that opposes the rotation of the lever. 4. 动力臂l1: The vertical distance from the fulcrum to the line of action of the force that causes the rotation of the lever. 5. 阻力臂l2: The vertical distance from the fulcrum to the line of action of the force that opposes the rotation of the lever. To determine the direction of the force and whether it is a force of rotation or opposition, consider the following: - A force that causes the rotation of the lever is the dynamic force. - A force that opposes the rotation of the lever is the resistance force. To draw the lever's force arm: 1. Find the fulcrum O. 2. Locate the points of application of the dynamic and resistance forces and their lines of action. 3. Draw vertical lines from the fulcrum to the points of application of the forces.The drawing technique for the moment arm has two methods: one using an arrow-tipped line, and the other using a dashed line with parentheses. The skill of drawing a moment arm with a right-angle triangle: extend the line perpendicular to the force line if it is not enough, and the other line through the origin O to connect is the moment arm.
