A construction crew wants to hoist a heavy beam so that it is standing up straight They tie a rope to the beam and secure its base (the bottom) Then they pull the rope to raise the top end of the beam off the ground. When the beam makes an angle of 40 degrees with the ground, the top of the beam is 8 feet above the ground There are telephone wires nearby and the workers are worried that the...
Explain the principle
and construction of a hydrometer. What is the purpose of the common
measurements of the specific gravities of an automobile’s radiator
coolant and battery electrolyte?
Explain the principle of operation of an ultrasonic sensor for
use in an industrial automation application. Answer should include
details on the type of target that can be detected, effect on
sensing distance of different target types, typical sensing
distance and what the term ‘blind zone’ refers to in relation to
these sensors.
