Common engineering questions resolved on JustAnswer


These Experts answer a huge variety of engineering questions, such as:


  • I am building a 3m long model submarine and need advice on how I can communicate/control the sub in salt water.
  • I’m building a raised concrete deck. I need help sizing the posts and the beams.
  • I am suspending a 100-pound dehumidifier from the joists in the furnace/mechanical room in my house. As the manufacturer recommends flat bar supports, what type of steel should I use (1018, 1144, 4130, or other), and how thick?
  • Does a stud wall that has nothing resting on top have any load bearing attributes?
  • We may need to retrofit our townhome in Los Angeles for earthquake, and the first step is to have an engineering study done. What is the right amount to pay for this study?

When preparing to consult with an Engineering Expert, be sure to have all the relevant weights and measurements on hand. The Expert will also need to know if you’re working on the project yourself or using a contractor. The more information you can provide, the more efficient the engineering consultation will be.
