    Why the Tacoma Narrows Bridge Collapsed

    Why the Tacoma Narrows Bridge Collapsed

    Wind can be one of the most critical and complicated loads on civil structures. The case of the Tacoma Narrows bridge is a well-known cautionary tale that’s discussed in engineering and physics classrooms across the world. Both resonance from vortex shedding and aeroelastic flutter contributed to the failure. When you push the envelope, you have to be vigilant because things that didn’t matter before start to become important (e.g. wind loads on lighter structures). Unanticipated challenges are a cost of innovation and that’s something that we can all keep in mind.

    Why evaluate legal information?

    Why evaluate legal information?

    In this video, a year 3 LLB student who is preparing a term paper with a substantial research component regularly consults his supervisor.

One piece of information is from a local real estate agent’s website summarizing the legal provision for the Hong Kong deed of mutual covenant agreements. Another piece of information is a court case covered in a Hong Kong land law blog.

    Why We Get Mad -- And Why It's Healthy

    Why We Get Mad -- And Why It's Healthy

    Anger researcher Ryan Martin draws from a career studying what makes people mad to explain some of the cognitive processes behind anger -- and why a healthy dose of it can actually be useful. "Your anger exists in you ... because it offered your ancestors, both human and nonhuman, an evolutionary advantage," he says. "[It's] a powerful and healthy force in your life."

    Why Tunnels Don't Collapse

    Why Tunnels Don't Collapse

    This video shows how simple reinforcement is used to prevent collapse of rock tunnels. Tunnels play an important role in our constructed environment as passageways for mines, conveyance for utilities, and routes for transportation. Rock bolts are a type of reinforcement for stabilizing rock excavations, usually made from steel bars or bolts. This simple construction method dramatically reduces the cost of making tunnels through rock safe from collapse.

    Why It's So Hard to Make Healthy Decisions

    Why It's So Hard to Make Healthy Decisions

    Why do we make poor decisions that we know are bad for our health? In this frank, funny talk, behavioral economist and health policy expert David Asch explains why our behavior is often irrational -- in highly predictable ways -- and shows how we can harness this irrationality to make better decisions and improve our health care system overall.

    Why Concrete Needs Reinforcement

    Why Concrete Needs Reinforcement

    This video shows more destructive testing to answer your questions about concrete. Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement.
