Study the diagram of a computer desk. Each member of the structure is under some type of force.

PART A: Is in tension because the weight of the computer is stretching it.

PART B: Is under compression because the weight of the computer unit and the members above that make up the desk, are pushing downwards and compressing it.

PART C and B: This is the same member but on the inside compression is taking place and on the outside it is being stretched (under tension).
 

MONITOR WEIGHS DOWN AND STRETCHES SUPPORT

WEIGHT OF COMPUTER UNIT COMPRESSES THE SUPPORT BENEATH THE SHELF

VERTICAL SUPPORT BENDS INWARDS BECAUSE OF WEIGHT OF COMPUTER. SIDE 'D' IS STRETCHED WHILST SIDE 'C' IS COMPRESSED

1. Draw a piece of furniture and label the struts and ties. With the aid of more detailed diagrams explain the forces acting on each of the important members.
