Answer to Question #348918 in Mechanical Engineering for Ze Rosa

Question

The I-beam design must satisfy the following requirements:

Maximum beam must not exceed the allowable stress.

Maximum deflection of the beam must not exceed the allowable stress.

Load which will be carried by the crane: 10026 Kg

Distance between the concrete walls: 14 meters

Distance from the ends of the track on which the trolley cannot run due to other machinery: 1.0 meters

Allowable normal stress in the I-beam: 260 MPa

Allowable beam deflection: 21 meters

The project will be assessed using the folllowing categories.

Conceptualise

Sketch the problem, showing relevant geometry, dimensions, support and loadings

Sketch e.g.: FBD or stress element as applicable

Identify Boundary conditions and other support conditions

Categorise

Identify problem type, solution strategy, relevant criteria and analyses

Write the governing equations

Identify unknowns

Make necessary assumptions

Identify material properties

Analyse

Solve the governing equations

Solve for unknowns or formulate problem to allow solution
