A typewriter is composed of__________________?
Show answer Hide answer
Answer: C. mechanism
Explanation
A typewriter consists of interconnected links designed to transmit motion from keys to typebars. When one link is fixed, the assembly transforms human input into precise mechanical output. An assembly of resistant bodies providing constrained relative motion defines a mechanism. Mechanisms form the building blocks of machines by converting input motion into tasks. Structures support loads without relative motion between their individual component links. Machines perform useful work and transmit significant mechanical power alongside mechanisms.
Typewriters represent classic examples of mechanical computing and linkage design. Office machinery historically relied entirely on complex mechanical linkages before electronics. Mechanism analysis ensures keys strike the paper cleanly without jamming or binding. A machine transmits significant power and performs heavy work, whereas a typewriter is a mechanism. A structure cannot transmit motion because its links are rigidly fixed relative to each other. Inversion is simply a method of fixing different links rather than the device classification.

Q5. A gas in a cylinder is compressed by a movable piston to half its initial volume, rejecting 300 kJ of heat while internal energy remains constant. What is the work done on the gas in N·m___________________?
Show answer Hide answer
Answer: B. 300,000 Nm
For an isothermal process with constant internal energy, work done equals the heat rejected. Heat rejected of 300 kJ converts directly to 300,000 Joules or N·m of work. Mathematical conversion from kilojoules to newton-m...
