During jogging, the joint speed limit is 10% of maximum joint speed.

• A. 5%
• B. 20%
• C. 10%
• D. 50%

Answer: (C)

Interpreting a safety limit as a percentage of the joint’s maximum speed means the allowable speed is that fraction of the joint’s peak capability. If the limit during jogging is 10% of maximum, you’re restricted to one-tenth of the joint’s maximum speed. The value that matches this exact limit is 10%. The other options would be speeds either below (5%) or above (20%, 50%) the stated limit, so they don’t satisfy the constraint.
