Melissa has developed a prototype of an app for schools. She wants to find beta testers who will give her effective feedback at low cost. Which steps would you advise her to take? Create your own social activity website or blog. Network with members of a chosen community. Locate the right communities of testers. Publish advertisements on community sites. Send out polite requests for beta testing.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
