Question 1

static load

Answer 1

loads that do not move

Question 2

dynamic loads

Answer 2

loads do move

Question 3

tension

Answer 3

the strength of an objects when it is being pulled apart

Question 4

examples of tension

Answer 4

tug of war, trampoline

Question 5

compression

Answer 5

opposite of tension, where the forces are directed towards each other, effectively squashing the object

Question 6

examples of compression

Answer 6

a vice, chair leg

Question 7

shear

Answer 7

forces act in opposite directions to each, but are not aligned with each other, causes parts of the objects to slide past each other

Question 8

examples of shear

Answer 8

scissors, knives when cutting

Question 9

bending

Answer 9

similar to shearing but the material will bend due to there being two pressure points against one

Question 10

examples of bending

Answer 10

seesaw, climbing a ladder

Question 11

torsion

Answer 11

acts to twist objects, force applied will attempt to rotate it in 360° in opposite directions at either end

Question 12

examples of torsion

Answer 12

propellers, screwdrivers
