Calculating Shear Stress in a Flange Coupling with 4 Bolts

Click For Summary
SUMMARY

The discussion focuses on calculating the shear stress in a flange coupling with four bolts subjected to a torque of 1500 Nm. The formula used for shear stress is fs = F/A, where F is the force acting on the bolts. The torque is converted to force using the equation t = F*r, which is essential for determining the shear stress. The calculated shear stress aligns with the back-of-the-book answer of 85.3 MPa.

PREREQUISITES
  • Understanding of shear stress calculations
  • Familiarity with torque and force relationships
  • Knowledge of flange coupling mechanics
  • Basic proficiency in using equations for mechanical engineering
NEXT STEPS
  • Study the derivation of shear stress formulas in mechanical systems
  • Learn about torque transmission in flange couplings
  • Explore the impact of bolt diameter on shear stress
  • Investigate failure modes in bolted connections
USEFUL FOR

Mechanical engineers, students studying torque transmission, and professionals involved in coupling design and analysis will benefit from this discussion.

Homework Statement



A flange coupling is use to transmit torque of 1500 Nm between two shafts. The coupling has four 8mm dia. bolts equally spaced on a PCD of 175mm. Determine the shear stress on the bolts

Homework Equations



fs=\frac{F}{A}

The Attempt at a Solution



Back of the book answer = 85.3MPa. but I don't know how they get this answer.

It's ok, disaster averted.

Just use t=F*r to convert the torque to a force acting on the bolt's.

Unfortunately TAFE forgot to give me this formula before giving me this question.
