Simulation block diagram and state equations

Simulation block diagram and state equations. See attached file for full problem description.

biomedical eggineering

An adjustable device is designed to apply a traction to stretch the tibia. It is attached to the tibia by rigid pins as illustrated below. There is a mechanism for length adjustable in the centre of the vertical section. Draw a free-body diagram for each of the three straight sections of the device, showing the forces and ...continues

equilibrium

When a body is in equilibrium, are the magnitudes of the unknown forces or moments independent of where they are located on the structure?

Trusses

Are the weights of members usually included in the analysis of truss structures?

Shear diagrams

A beam is under applied loads shown. How can I describe the shear diagram for sections I through III?

Method of Joints

A truss is loaded as shown. How do I find the magnitude of the force in members DB and BF? Can it be done without the equations of equilibrium?

Reaction forces

A horizontal beam under load can roll along a vertical guide as shown. What are the reaction loads at A? Shear? Axial?

structural analysis

A 10ft beam has applied forces F1 and F2 as shown. The influence functions for the shear and bending moment at point B are als shown. For forces F1=10lbs and F2=20lbs, how do I find the shear and bending moment at point B?
