Determine the force exerted on the (rigid) supports when the temperature becomes T2 = 18OC. The material properties and cross-sectional area of each bar are given.
What difference does the tightening of bolt in the friction grip joint make to the load at first slip and the failure load. Why is the correct tightening of friction grip bolts important?
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. How do you determine the volume flow rate (Q) o
Many years ago, well-known architect Frank Lloyd Wright designed a mile-high skyscraper, which has never been built. Suppose that in such a building, steam for the heating system ent
An equal-tangent crest vertical curve is designed with a PVI at station 110+00 and a PVC at station 107+43.3. if the high point is station 110+75.5 what is the design speed of he curve?
A venturi meter is placed in a pipeline to measure the flow rate of the liquid flowing through that pipe.The meter inlet and throat are connected by the two legs of a mercury manometer.
A paved parking lot section has a uniform slope over a length of 100 m (in the flow direction) from the point of a drainage area divide to the inlet grate, which extends across the lot width of 30 m.&
A constant head permeability test was conducted on a clean sand sample. The diameter and length of the test specimen were 10 cm and 12 cm respectively.
A 45 kg machine is placed at the end of a 1.6 m long cantilever beam of elastic modulus 200 x 109 N/m and cross-sectional moment of inertia 1.6 x 10-5 m4. As it operates, the machine produces a harmon
