Term | Definition |
---|---|
projection line | A horizontal or vertical line that can be used to locate entities in an adjacent view. |
prototype | a full scale working model of a design intended to have complete,or almost complete,form,fit,and function of the intended design. a prototype is used to test a design concept by making actual observations and making any necessary adjustments. |
rapid prototyping | the procces of creating a solid model in a computer-controlled machine using a CAD desing file. |
resistance | a measure of the resistance a material or component has to the flow of electricity (charge). The higher the electrical resistance,the more resistant the material or components is to the flow of charge (current). |
reverse engineering | a strategy used to find answers to questions about an exsiting product that are later used in the design of another product. |
right brain | the right hemisphere of the cerebullum where it is beleived simultaneous, holistic, spatial, and relational information processing are favored. |
rotational velocity | The rate of change of angle with change. Two typical units of rational velocity are radians/seconds (rad/s) and deg/secons (deg/s). |
safety factor | a measure of how much the product is over built and the ratio of the ultimate stress(breaking point)and the working stress(maximum expected load). |
schematic | a diagram of a system that uses graphic symbols to represent pneumatic, hydraulic, or electrical components. |
science | a descriptive discipline that makes observations through experimental investigation to explain physical and natural phenomena. science seeks to answer the question "why?". |
