Number of Bolts required Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Bolts in Joint = External Force on Bolt/Primary Shear Load on Bolt
n = P_e/P₁'
This formula uses 3 Variables

Variables Used

Number of Bolts in Joint - Number of Bolts in Joint is simply defined as the number of bolts that are under our consideration in a jointed assembly.
External Force on Bolt - (Measured in Newton) - The External Force on Bolt is defined as the forces caused by an external agent present outside of the system.
Primary Shear Load on Bolt - (Measured in Newton) - Primary Shear Load on Bolt is defined as the force acting in a direction parallel to a surface or to a planar cross-section of the bolt.

STEP 1: Convert Input(s) to Base Unit

External Force on Bolt: 6000 Newton --> 6000 Newton No Conversion Required

What is a fastener?

A fastener or fastening is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components.

How to Calculate Number of Bolts required?

Number of Bolts required calculator uses Number of Bolts in Joint = External Force on Bolt/Primary Shear Load on Bolt to calculate the Number of Bolts in Joint, Number of Bolts required is the total load applied on a structure divided by the tensile or shear capacity of an individual bolt, adjusted by a safety factor, gives the number of bolts needed to safely support the load. Number of Bolts in Joint is denoted by n symbol.

How to calculate Number of Bolts required using this online calculator? To use this online calculator for Number of Bolts required, enter External Force on Bolt (P_e) & Primary Shear Load on Bolt (P₁') and hit the calculate button. Here is how the Number of Bolts required calculation can be explained with given input values -> 4 = 6000/1500.

FAQ

What is Number of Bolts required?

Number of Bolts required is the total load applied on a structure divided by the tensile or shear capacity of an individual bolt, adjusted by a safety factor, gives the number of bolts needed to safely support the load and is represented as n = P_e/P₁' or Number of Bolts in Joint = External Force on Bolt/Primary Shear Load on Bolt. The External Force on Bolt is defined as the forces caused by an external agent present outside of the system & Primary Shear Load on Bolt is defined as the force acting in a direction parallel to a surface or to a planar cross-section of the bolt.

How to calculate Number of Bolts required?
