Final answer:
The torque of the fastener is 34.389 N·m.
Step-by-step explanation:
To calculate torque, we use the formula Torque = Force x Lever Arm. In this case, the force is 12.25 lbs and the lever arm is 2.5 ft. Converting the force to Newtons (1 lb = 4.44822 N) and the lever arm to meters (1 ft = 0.3048 m), we can calculate the torque as follows:
Torque = (12.25 lbs x 4.44822 N/lb) x (2.5 ft x 0.3048 m/ft) = 34.389 N·m.
