What is a bending moment diagram?
A bending moment diagram is a graphical representation of the bending moment forces along a structural member, such as a beam. The diagram shows the values of the bending moment along the length of the beam.
What is a shear force and bending moment?
By showing how the shear force and bending moment vary along the length of a beam, they allow the loading on the beam to be quantified. They are often used as a starting point for performing more detailed analysis, which might include calculating stresses in beams or determining how beams will deflect.
How is a bending moment calculated?
The bending moment at any point along a structural element can be calculated by multiplying the force applied to the beam by the perpendicular distance from the point of interest to the line of action of the force. The unit is kilonewton-meters (kNm) in Europe and foot-points (ft-lb) in the US.
Where can I find a structural engineering spreadsheet for beam design?
Structural engineering spreadsheet collection for beam design using excel are available for purchase and can be found under each beam type. Additional information regarding engineering beam design theory and the assumptions that have been made can be found Here. Fixed End Beam. PL at Any Point Cantilever Beam.

What size inverter can I use with a 48v lithium battery
To safely and efficiently use a 48V lithium battery, choose a 48V-rated pure sine wave or hybrid inverter, sized to your daily load, and compatible with CAN or RS485 BMS communication. This setup ensures reliable solar operation, long battery life, and energy cost savings. . So I have made it easy for you, use the calculator below to calculate the battery size for 200 watt, 300 watt, 500 watt, 1000 watt, 2000 watt, 3000 watt, 5000-watt inverter Failed to calculate field. Note! The battery size will be based on running your inverter at its full capacity Instructions!. Many off-grid or solar system owners ask how to choose the right inverter for a 48V lithium battery setup. The formula is: Inverter Size (Watts) = Total Load (Watts) / System Voltage (48V). You've got a full battery, but zero power. Always check the battery's max discharge rate (C-rate) to avoid exceeding safe limits. When sizing for 24V or 48V. . [PDF Version]
