Effort using Length and Load Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effort on Lever = Length of Load Arm*Load on lever/Length of Effort Arm
P = l₂*W/l₁
This formula uses 4 Variables

Variables Used

Effort on Lever - (Measured in Newton) - Effort on Lever is the force applied on the input of the lever to overcome the resistance to get the work done by the machine.
Length of Load Arm - (Measured in Meter) - Length of Load Arm is the length of the arm of a lever on the end on which the load is exerted.
Load on lever - (Measured in Newton) - Load on lever is the instantaneous load that is resisted by the lever.
Length of Effort Arm - (Measured in Meter) - Length of effort arm is defined as the length of the arm of the lever onto which the effort force is applied.

STEP 1: Convert Input(s) to Base Unit

Length of Load Arm: 95 Millimeter --> 0.095 Meter (Check conversion here)
Load on lever: 2945 Newton --> 2945 Newton No Conversion Required
Length of Effort Arm: 900 Millimeter --> 0.9 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P = l₂*W/l₁ --> 0.095*2945/0.9

Evaluating ... ...

P = 310.861111111111

STEP 3: Convert Result to Output's Unit

310.861111111111 Newton --> No Conversion Required

FINAL ANSWER

310.861111111111 ≈ 310.8611 Newton <-- Effort on Lever

Bending stress in lever of elliptical cross section

Go Bending Stress in Lever Arm = (32*(Effort on Lever*((Length of Effort Arm)-(Diameter of Lever Fulcrum Pin))))/(pi*Minor Axis of Lever Ellipse Section*(Major Axis of Lever Ellipse Section^2))

Reaction Force at Fulcrum of Lever given Effort, Load and Contained Angle

Go Force at Lever Fulcrum Pin = sqrt(Load on lever^2+Effort on Lever^2-2*Load on lever*Effort on Lever*cos(Angle Between Lever Arms))

Bending stress in lever of rectangular cross section

Go Bending Stress in Lever Arm = (32*(Effort on Lever*((Length of Effort Arm)-(Diameter of Lever Fulcrum Pin))))/(pi*Width of Lever Arm*(Depth of Lever Arm^2))

Bending stress in lever of elliptical cross section given bending moment

Go Bending Stress in Lever Arm = (32*Bending Moment in Lever)/(pi*Minor Axis of Lever Ellipse Section*(Major Axis of Lever Ellipse Section^2))

Bending stress in lever of rectangular cross section given bending moment

Go Bending Stress in Lever Arm = (32*Bending Moment in Lever)/(pi*Width of Lever Arm*(Depth of Lever Arm^2))

Reaction Force at Fulcrum of Lever given Bearing Pressure

Go Force at Lever Fulcrum Pin = Bearing Pressure in Fulcrum Pin of Lever*Diameter of Lever Fulcrum Pin*Length of Lever Fulcrum Pin

Maximum bending moment in lever

Go Bending Moment in Lever = Effort on Lever*((Length of Effort Arm)-(Diameter of Lever Fulcrum Pin))

Effort Force Applied on Lever given Bending Moment

Go Effort on Lever = Bending Moment in Lever/(Length of Effort Arm-Diameter of Lever Fulcrum Pin)

Load using Lengths and Effort

Go Load on lever = Length of Effort Arm*Effort on Lever/Length of Load Arm

Effort using Length and Load

Go Effort on Lever = Length of Load Arm*Load on lever/Length of Effort Arm

Reaction Force at Fulcrum of Right Angled Lever

Go Force at Lever Fulcrum Pin = sqrt(Load on lever^2+Effort on Lever^2)

Leverage

Go Mechanical Advantage of Lever = Length of Effort Arm/Length of Load Arm

Effort using Leverage

Go Effort on Lever = Load on lever/Mechanical Advantage of Lever

Mechanical Advantage

Go Mechanical Advantage of Lever = Load on lever/Effort on Lever

Load using Leverage

Go Load on lever = Effort on Lever*Mechanical Advantage of Lever

Effort using Length and Load Formula

Effort on Lever = Length of Load Arm*Load on lever/Length of Effort Arm
P = l₂*W/l₁

What is lever?

A lever is defined as a mechanical device in the form of a rigid bar pivoted about the fulcrum to multiply or transfer the force.
