Question 4

A bolt weighting 10 N is accidently dropped down a 4 m long vertical cast-iron pipe which is closed by means of a rigid flange at the end. Calculate:

4.1       The instantaneous stress induced in the material of the pipe if the inside diameter of the pipe is 200 mm and the pipe wall thickness is 10 mm.                        

4.2       The instantaneous elongation of the pipe.                                                     

4.3       The gradually applied load that would produce the same stress as in 4.1.   

            E = 140 GPa

Pressurized water (pin= 10 bar, Tin= 110°C) enters the bottom of an L= 10-m-long vertical tube of diameter D= 88 mm at a mass flow rate of m˙⁢= 1 kg/s. The tube is located inside a combustion chamber, resulting in heat transfer to the tube. Superheated steam exits the top of the tube at Pout= 7 bar, Tout= 600°C. Determine the change in the rate at which the following quantities enter and exit the tube: (1) the combined thermal and...

The San Andreas is long but is a vertical fault, so only ~25 km of down-dip width is cold enough to break in an earthquake (i.e. below 25 km depth, the rocks are too warm to fail in a brittle earthquake and instead deform in other ways). Imagine a 500 km length of the fault breaks, slipping 10 m (this huge earthquake is unlikely but not impossible). What magnitude would this earthquake be? Area is width multiplied by length... and...

A horizontal beam of length 4.07 m and weight 150 N is attached to a vertical wall at a right angle. There is also a support wire of length 5.01 m which attaches the far end of the beam to the wall from above. Off of the far end of the beam also hangs an object of weight 290 N. A) What is the magnitude of the tension in the support wire? B) What is the horizontal component of the...

A vertical spring with k = 490 N/m is standing on the ground. You are holding a 5.8 kg block just above the spring, not quite touching it. (a) How far does the spring compress if you let go of the block suddenly? m (b) How far does the spring compress if you slowly lower the block to the point where you can remove your hand without disturbing it? 0.116 m is the answer I got and know how to...

A box of mass 1kg is placed on a vertical spring (k=1000N/m) and pushed down so that the spring is compressed by 0.3m from the unstretched length. When the spring is released, what is the maximum height above the initial position (when the spring is compressed) the box rises?
