About this document
Max Moment Calculation for Crane Boom by Christina Nunez is a document available to read on EtoBox.
The document describes solving a statics problem to determine the angle θ that results in the maximum moment about point O. A force P of 6 kN acts at the end of an 8 m long crane boom. The position vectors rA and rB are written. The moment MP is expressed as a function of θ. Taking the derivative and setting it equal to zero allows solving for the value of θ that maximizes the moment. This yields θ ≈ 0.55 radians or 31.5 degrees. Plugging this back into the moment equation gives the maximum moment of 4.80 ×
