Lab 8: Forces on Submerged Objects
A. Background Information
When an object is submerged in a fluid (liquid or gas), it will experience a force due to the
pressure exerted by the fluid on the object. The amount of force depends on the density of the
fluid
Lab 6: Using the Newton Raphson Algorithm to Solve the 2-Link Robot
Transcendental Equations
Introduction
The figure below includes a diagram of the 2-link robot arm along with the equations for the x
