A simply supported wood beam with overhang is subjected to uniformly distributed load q. The beam has a rectangular cross section with width b 5 200 mm and height h 5 250 mm. Determine the maximum permissible value q if the allowable bending stress is s all 5 11 MPa, and the allowable shear stress is all t 5 1.2 MPa.

What is the main objective of using reheat rankine cycle?

Ahelical coil spring has a mean diameter of 50 mm, a wire diameter of 5.5 mm and is wound with a pitch of 10 mm. the spring steel has an ultimate strength of 1250 mpa. find the force needed to compress the spring solid and the wire stress in this condition. state whether the spring will return to its initial length.

Acompressor compresses a gas, a pump compresses a liquid. for a given pressure ratio, why does it take more work to compress a gas in a compressor than a liquid in a pump? a)- for a given pressure ratio the average specific volume for a gas is much higher than the average specific volume for a liquid. b)- there is no difference. the only difference is the amount of heat generated (not work) c)- for a given pressure ratio the average volurge for a gas is much higher than the average volume for a liquid. d)-there is no difference
