Hello my wonderful students!!! Listen closely...are you listening??? This is your science teacher Ms. Yates. I know, I know. I just saw you a few hours ago. Remember the awesome reminders, updates, and fantasticness that I promised you?? It is here. Yep!! Right here. Remember to check it out daily. The rewards will be worth your time. Assignments that you forgot about or were absent for? Here!! Notes you may have missed?? Here too!!! Announcements?? Yep!! And, fantastic reminders of all the cool stuff we did today...All here and more!! See you tomorrow. Or Monday, if you are so awesome that you are reading this over the weekend.

DSN Animation: What is Tension/Compression?
After watching the video, explain the forces of tension and compression in a suspension bridge.
The weight of the live load and the weight of the bridge push down, applying tensional force to the small cables, which pull down on the main cable applying tensional force to the main cable. the main cable pulls the towers in but the towers are steadied by more cables which are anchored into the ground. Together the cables cancel out the side to side force applied on the towers and compressing them. Jack
In a suspension, there are ropes, cables and pillars. When the main deck is pulled, the cables on the ropes are being pulled out, putting them in tension. Those cables pull on the rope, which is placed between the pillars, putting the rope in tension. Then, the rope pushes down on the pillars, putting the pillars in compression. That is how forces act in a suspension bridge.
As the deck gets pushed down by traffic the ropes pull down causing tension on the main ropes putting them in tension which then push down on the on the supporting towers. alexa
The bridge pulls down on the cables created tension which the cables pull down on the rope tying them to the beam creating more tension and finally the rope is putting compression on the supporting rod Nicole

ReplyDeletethe forces of tension and compression are...
ReplyDeletepulling which is for tension <- ->
and "pushing" -> <- which is compression

deck pulls on ropes, ropes pull on bigger ropes, and bigger ropes pull on the towers

the vertical ropes pull on the main cable, which is tension. While the main cables push down in compression

ReplyDeleteThe bottom of the deck pulls on cables, that is tension. The top of the dech pushes the cables down, that is compression.

The suspension cables have tension and the supporting tower are in compression. Lastly the hanging cables are under tension
