We are in build season, so here are a couple of build related questions adapted from an Engineering web site (engcom.net):

What name is given to a thin plate with a hole that is typically used to distribute the load of a threaded fastener , such as a screw  or nut  and is also often used as a spacer

Beginning with the letter "M", what name is given to a type of hammer , often made of wood  or other soft material and with a relatively large head
