Q: Are machines complex systems that consist of structural elements? ¶
A: Yes, and mechanisms and control components and include interfaces for convenient use.
Q: Are machines worked out by Italian scientist Galileo Galilei in 1600 in Le Meccaniche? ¶
A: Yes, He was the first to understand that simple machines do not create energy, they merely transform it.
Q: Are machines systems consisting of a power source and actuators that generate forces and movement? ¶
A: Yes, and a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement, a controller with sensors that compare the output to a performance goal and then directs the actuator input, and an interface to an operator consisting of levers, switches, and displays.
Q: Are machines developed by Franz Reuleaux? ¶
A: Yes, and who collected and studied over 800 elementary machines.
Q: Were machines called? ¶
A: Yes, and began to be studied from the standpoint of how much useful work they could perform, leading eventually to the new concept of mechanical work.
Q: Are machines elementary examples of kinematic chains or linkages that are used to model mechanical systems ranging from the steam engine to robot manipulators? ¶
Q: Were machines discovered by Leonardo da Vinci? ¶
A: Yes, but remained unpublished in his notebooks.
Q: Is a machine a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motion? ¶
Q: Are machines commonly reckoned to be Six in Number? ¶
A: Yes, and viz.
Q: Is a machine "a device for applying power or changing its direction"? ¶
