Point load from mass

Distributes mass as an area load over a given area using the supplied gravitational acceleration.

Converts a line load to a point load for assigned tributary length L_tr.

Multiplies area load by tributary area to estimate a column load.

Combines three line loads with factors entered manually by the user; it is not a combination from any specific code.

Divides total load by support count without imposing a support type.

Calculates self-weight from density, volume, and gravitational acceleration.
