please i need help cause i don't know y we r doing this experiment in the first place any one ?
um i think you have that wrong tensile strength is a measurement of how strong something is when stretched so i will assume you mean... MORTAR.. not motor testing the strength of mortar is important for knowing how strong it is when bonding things like cement blocks together when building structures, or for doing a parging coat with .. etc..
You sure it is called cement motors. I know tensile strength of cement briquettes ( used to test the strength of cement in to know if satisfactory for gripping on to rebar) , but sorry never heard tensile of cement motors. Try typing the exact question you were given.
