Why a Longer Spanner Opens Any Bolt: Moment of a Force | Textbook to Workshop #Shorts

Textbook to Workshop · 02: Moment of a force

Bolt won't budge? Don't push harder. Push farther.

• Your physics textbook: Moment = Force × distance
• A bolt needs 50 N·m. With a 0.10 m spanner that's 500 N. With 0.25 m, 200 N. With 0.50 m, just 100 N. 5× longer, 5× easier
• In the workshop, a torque wrench clicks at exactly the torque you set. Too loose and it rattles off. Too tight and the bolt stretches

Can you solve it? A bolt needs 60 N·m and your spanner is 0.3 m long. How much force do you need? Answer in the comments.

This is everyday work at ISTC, after Class 10, AICTE approved:
• Diploma in Mechanical Engineering (Tool & Die), 3 years
• Advanced Diploma in Die & Mould Making, 4 years

FARTHER BEATS HARDER.
