What does Hooke’s Law explain ?

If the external force is larger than the
(1.)size
(2.)volume
(3.)elastic limit
of material, it may result in permanent deformation in the shape and size of the object. This characteristic is known as the
(4.)material behavior
(5.)elastic behavior
(6.)plastic behavior
of an object.

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Inadequate stores control is not an obstacle to effective work order system. (clo4) a)-true b)-false
