Which of the following are true in case of machine and structure
(A). The members of structure do not move relative to one another.
(B). In a structure energy is transformed into useful work.
(C). The links of a machine may transform both power and motion.
(D). The members of a structure transmit forces only.
Choose the correct answer from the options given below:
Show Hint
To easily remember the distinction:
- Machine = Motion + Force transmission + Energy modification.
- Structure = Only Force transmission (Static, zero relative motion).
