- The machine below forms metal plates through the application of force. Two toggles (ABC and DEF) transfer forces from the central hydraulic cylinder (H) to the plates that will be formed. The toggles then push bar G to the right, which then presses a plate (p) into the cavity, thus shaping it. In this case, the plate becomes a section of a sphere. If the hydraulic cylinder can produce a maximum force of F = 10 kN, then what is the maximum P value (i.e. Pmax) that can be applied to the plate when θ = 35°? Also, what are the compressive forces in the toggle rods in that situation? Finally, what happens to Pmax and the forces in the rods as θ decreases in magnitude?arrow_forwardAnswer all the questions What is the minimum value of capacitor C1 required such that Vfiltered does not drop below 8 V? Use the design equation(but make sure you use the right “frequency” and the correct ripple voltage). Show your calculations. Display your circuit in circuit js. Display Vsecondary (can use the voltage across the added 100 kΩ resistor) and Vfiltered in a “Combined Scope”. Display VDC in a separate scope: a) Turn on “Max Scale”, “Show Peak Value” and “Show Negative Peak Value”: b) Run the simulator and adjust the window and simulation speed and time step to be able to see a couple of cycles. Include a screen capture Document the minimum and maximum values for Vfiltered in your lab report. Is Vfiltered maintained to be above 8 V? By how much? Why? Explain the waveform shape captured Vfiltered. It may help your understanding to rerun the simulation with C1 removed and compare that waveform for Vfiltered to that capturedarrow_forward40m 150N B 40marrow_forward
