Arod for a certain hydraulic cylinder behaves as a fixed-free column when used to actuate a compactor of industrial waste. its maximum extended length will be 2000mm. if it is to be made of sae 1144 oqt 1300 steel, determine the required diameter of the rod for a design factor of 2.0 for an axial load of 80.0 kn. pick the closest answer in mm. a) 24 b) 116 c)73 d)47

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
