A company wants to design a new prosthetic arm for young adults. The new arm must bend at the elbow to allow the user to carry out household chores such as laundry and grocery shopping. A load of laundry and a bag of groceries each weighs about 3 kg. The target users cannot afford an expensive device so the arm must cost under $100 to produce. It must also have no sharp edges, as these would risk injury to the user and others. Sort the criteria and constraints into their given categories. Write the correct answer.

Can carry 3 kg (criteria or constraint)?

A student is developing a grabbing device for people who use wheelchairs. The device needs to meet two criteria: it must be able to reach up to 1 meter away and it must be able to pick up items that are 10 cm wide. She develops a model and tests it to determine if it meets the criteria. Which of the following scenarios would test that the grabber can pick up items that are 10 cm wide?

A prosthetics manufacturing company has decided to redesign one of its prosthetic legs. The new design should be less expensive to produce but should still support the same amount of weight as the current design. Five teams presented five different design solutions. Tests showed that none of the designs met all the criteria for success. What should the company do next?

• Move forward with the design that met most of the requirements in order to save time

• Compare data from the tests in order to combine the best characteristics from each solution into a new and improved design solution

• Have each team continue modifications and testing on their own design until they produce test results that show a more promising solution

• Revise the given criteria so that at least one design solution is able to meet all of the requirements

Students are developing ramps for their school. They want to provide wheelchair users in the school with easy and safe access to their classrooms so that they can move around without assistance. What should they consider when deciding where to place their ramps? Check all the answers that apply.

• How much space each ramp would require

• The number of students in wheelchairs at the school

• Cost of materials

• The location of classrooms around the school

Ayisha analyzes the data she has collected and decides she can make improvements by changing the materials she uses in her next prototype. She determines that she will definitely use titanium in her new design solution.

Which piece of evidence will help her explain why titanium should be included in her next prototype?

• Prototype B had a greater mass than the other prototypes.

• Prototype B was the only prototype to use titanium. It supported the most weight.

• Prototype B used plastic and so did Prototypes A and D. Prototype B also used titanium.

• Prototype B and Prototype A both used metals, but they were different types of metal.
