The system has four inputs. The first two, a and b, represent a number in the range 0 to 2 (3 is not used). The other two, c and d, represent a second number in the same range. The output, y, is to be 1 if and only if the two numbers do not differ by more than 1.

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

What is the coefficient of kinetic friction μk between the block and the tabletop?
