In the vessel there is an absolute pressure pe and a temperature a, heat is subsequently supplied to the gas in the vessel. Consider the air as an ideal gas. Consider the state change reversible. m=250 g; p = 180 kPa ; n = 20°C: Q=4500); r= 287 kg 1-K-1;*= 1.4 Write the temperature in the vessel after heating [°C] t2 = [°C] Write the pressure pe in vessel after heating [kPa] P2 = [kPa] There is a straight beam of rectangular cross-section c x 2c of length, which is rotary supported at one end (A), at the other end (B) slidably supported and at point Cloaded by a Tho hoam is made of a material with yield strength o which we
Write the pressure puin vessel and P2 [kPa] There is a straight beam of rectangular cross-section ex 2c of length, which is rotary supported at one end (A) at the other end (B) slidably supported and at point Cloaded by a solitary force F as shown. The beam is made of a material with yield strength ox, which we consider to be ideally elastic plastic (for an approximation according to Prandt, see the picture) 1 A с 2.4 <= 30 mm: 300 mm x 200 N mm Choose the size of the plastic modulus of the cross-section in bending W.
