The piston cylinder device shown in the attached image contains a fluid that can be stirred by a rotating shaft. The outer surface of the device is covered with a thick layer of insulation. The shaft imparts 50 kJ to the fluid during a process in which the pressure is held constant at 130 kPa as the piston moves outward.
If the initial energy of the fluid increases by 20 kJ during the process, What is the axial displacement of the piston?
Please show as much work as possible to receive 5 stars!!!! thanks!!!! :D
The beam shown in the attached image is connected to a pin at A and rests on a roller at B. Neglecting the weight of the beam, draw a free-body diagram of the beam.
The roller is under the very end of the right side of the beam. Sorry for the cut off image. it is the center image.
Find the resultant force for the forces in the attached image by resolving the forces into there x and y components.
see attached image for graph.
please show as much work as possible for 5 stars!! thanks!!! Sorry for the size of the pic by the way, im trying to fix it.
