hockey sticks are made from a material that can resist indentation (plastic deformation) and shock when it comes into contact with a puck or the ice. The material also has to be lightweight to be easily handed to by a player. Heres a list of possible materials to choose from:

Materials/Properties

steel> hard, resilient, ductile, and high density.

carbon fire> low density, hard, resilient, resistance to corrosion

polymethyl (Arcylic)> hard, malleable, brittle

Questions

name at least one constraint the hockey stick can experience.

Which material, in the table above, seems to be most suitable to make a hockey stick? explain the reasoning behind your choice by properly establishing the connection between mechanical properties and desired outcomes in this technical object..

Grill pans are made from material that can easily transfer high heat to the food even at low temperature apart from the fact that pan should be able to tolerate high temperature, it must not break or change its shape if the hot pan dropped by accident. You also need to select the material for the pan's handle so you can safely hold the hot pan. Heres is the list of possible materials to choose from

aluminum

low density

medium hardness

high thermal conductivity

malleability (especially at high temperatures)

corrosion resistance

cast iron

very hard

very dense

resilient

high thermal conductivity

resistance to high temperature

soft wood

low density

medium hardness

low thermal conductivity

elastic

PVC (plastic)

hard

low density

not resistant to high temperature
