What is the minimum diameter of a brass rod if it is to undergo a N tension without exceeding the elastic limit? A cubical metal block 40 cm on a side is given a shearing force of , N at the top edge. What is the shear modulus if the upper edge deflects a distance of 0.
How large a load can a 0. A metal wire increases its length by 2 mm when subjected to tensile force. What elongation can be expected from this same force if the diameter of the wire was reduced to one-half of its initial value?
Suppose the metal wire maintains its diameter, but doubles its length. What elongation would be expected for the same load? I am a first year teacher as well and was completely lost until I found this information. Thanks for sharing!! Like Liked by 1 person. These are just what my 6th grade right brained learner needs! I appreciate all of your hard work and willingness to share. Liz, Thank you for the great resource. I was told by a fellow science teacher this web site has great activities.
He was absolutely correct! I am so thankful for your interactive notebook pages. The cut and pastes are wonderful and I love the sorting activities. Thank you so much for sharing your expertise and digital resources with us. It has been extremely helpful to me as a new teacher. Thank you so much for re-posting these from your old website!! I use them nearly every year and LOVE them!
