What are the 5 types of constraints?
Compression, tension, torsion, deflection, shearing
Description of compression
Forces that tend to crush it
Description of tension
Forces that tend to stretch it
description of torsion
forces that tend to twist it
description of deflection
forces that tend to bend it
description of shearing
forces that tend to cut it
hand squeezing a wet sponge is an example of which constraint?
compression
a foot crushing a can is an example of which constraint?
compression
copper stretched into a wire is an example of which constraint?
tension
an earthquake twisting a bridge is an example of which constraint?
torsion
a hand wringing a wet towel is an example of which constraint?
torsion
fish bending a fishing rod is an example of which constraint?
deflection
clothes weighing down a clothesline is an example of which constraint?
deflection
scissors cutting paper is an example of which constraint?
shearing
metal cutters trimming shapes from metal is an example of which constraint?
shearing
whats the symbol for compression?
two arrows facing each other
whats the symbol for tension
two arrows facing apart
whats the symbol for torsion?
two arrows in a circular shape
whats the symbol for deflection?
three arrows: middle one facing up and other two downwards
whats the symbol for shearing?
two arrows facing each other except the arrowhead is half off???
what does constraint mean?
the effects of eternal forces upon objects
what is material deformation?
constraints have a tendency to deform objects/change their shape
what are the three types of material deformation?
elastic, plastic, fracture
what is the description of elastic?
a temporary change in the shape or dimensions of the material. When constraint is removed, the material returns back to its original shape.
