15. Copyright © 2006 Thomson Delmar Learning. ALL RIGHTS RESERVED. 15 Assessment Questions What are the three biting forces? Tensile, compressive, and shearing What is the term for two different metals meeting and creating small electrical shocks? Galvanism or galvanic shock Why must zinc phosphate cement be mixed on a cool glass slab? Because it has an exothermic reaction
