The Jib Arm Deflection Calculator serves as a crucial tool in engineering and construction, aiding in the determination of the deflection (bending or deformation) of a jib arm under load. It calculates the extent to which a jib arm, subjected to a specific load at its end, will bend or deflect. This is essential in designing jib arms for cranes, booms, or other structural elements to ensure their safety and functionality.

Formula of Jib Arm Deflection Calculator

The calculation formula for jib arm deflection is represented as:

δ = (5 × P × L^3) / (384 × E × I)


  • δ represents the jib arm deflection, measured in inches or meters.
  • P stands for the load applied at the end of the jib arm, denoted in pounds or kilograms.
  • L signifies the length of the jib arm, measured in inches or meters.
  • E denotes the modulus of elasticity of the jib material, expressed in pounds per square inch or Pascals.
  • I represents the moment of inertia of the jib arm cross-section, measured in inches^4 or meters^4.

This formula provides a straightforward method to calculate the deflection, enabling engineers and construction professionals to make informed decisions regarding the design and materials used in jib arm construction.

Example of Jib Arm Deflection Calculator

Suppose a jib arm has a length (L) of 100 inches, a load (P) of 500 pounds, a modulus of elasticity (E) of 2,000,000 Pascals, and a moment of inertia (I) of 1,000 inches^4. Plugging these values into the formula:

δ = (5 × 500 × 100^3) / (384 × 2,000,000 × 1,000) δ ≈ 0.651 inches

This example demonstrates the calculation process, providing users with a clear understanding of how to utilize the calculator.
