For each of the following systems state the functional form of its input/output relation [linear (L), semi-log (SL), log-log (LL)] and how its output changes with increasing input (decreases, remains constant, or increases).
(a) Four strain gages mounted on a cantilever beam with an input (I) of force applied at its end and an output (O) from the Wheatstone bridge containing the strain gages.
(b) The relative humidity sensor.
(c) The photocell with its voltage divider.
(d) The with its voltage divider.
(e) A RTD without a voltage divider.
