Figure Q3 shows a hydraulic cylinder made of AISI 1050 CD material under external loading and internal pressure. The external loading includes torque (T-300 kN.m) and pressure (P.-30 MPa). The internal pressure is created by applying force to the piston (P, F/A). The force applied to the piston fluctuates between 1000 kN and 5000 kN. The inner diameter of the cylinder and diameter of piston are d = 250 mm. The inner surface of the cylinder is machined and its temperature is 450° C.

Machine Desi... 5- Consider a system of two springs, with stiffnesses k, and k2 arranged in parallel as shown in in the below figure. The rigid bar to which the two springs are connected remains horizontal when the force F is zero. Determine the equivalent spring constant of the system that relates the force applied (F) to the resulting displacement (x) as: F = Kex Hint: Because the spring constants of the two springs are different and the distances L1 and L2 are not the same, the rigid bar will not remain horizontal when the force F is applied F PDF MECHA213 MECHA213 Week 9- Parts-2- PDE 00000000000 000000000000
