35. A student weighs 150 lbs (F) and is standing on a beam which spans 96 inches (L). The Modulus of elasticity (E) of the beam is 1,200,000 lb/in2 and the moment of inertia (I) is 12 in4. Calculate the beam deflection (∆MAX). a. .192 in b. .340 in c. 57,600 in d. .0000208 in

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point. the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

With increases in magnification, which of the following occur? a. the field of view decreases. b. the ambient illumination decreases. c. the larger parts can be measured. d. the eyepiece must be raised.
