The phasor technique makes it pretty easy to combine several sinusoidal functions into a single sinusoidal expression without using trigonometric identities. However, you cannot use the phasor technique in all cases. Select the expressions below for which the phasor technique cannot be used to combine the sinusoids into a single expression. Check all that apply. View Available Hint (s) Check all that apply. - 100sin (10,000t+90∘) + 40sin (10,100t-80∘) + 80cos (10,000t) 100cos (500t+40∘) + 50sin (500t-120∘) - 120cos (500t+60∘) 25cos (50t+160∘) + 15cos (50t+70∘) 45sin (2500t-50∘) + 20cos (1500t+20∘) 75cos (8t+40∘) + 75sin (8t+10∘) - 75cos (8t+160∘)

Write a new ARMv8 assembly file called "lab04b. S" which is called by your main function. It should have the following specifications: Create a function that computes factorials: n! = n · (n - 1) · ... · 3 · 2 · 1. Use the my_mul function in question 1 for all multiplications Use the concept of recursion. Do NOT directly use the concept of iteration. Do not forget that using the recursion is the same as using the STACK. Make sure you comment on the code. Demonstrate your code running to the TA. Turn in your lab04b. S file here when complete.

A colleague stops by your desk to ask you about some lab and field results they are comparing. The Mohr's circle they constructed based on the field stresses does not touch the failure envelope constructed from lab results. Your colleague is concerned that the new lab technician may not be conducting shear tests properly, despite multiple tests confirming the shear strength parameters.

Do you agree, or not? (Remember to justify your answer).

A machine operates using air flow under steady conditions with the following inlet and exit flow parameters. At the inlet, the pressure is 1.75 MPa at a temperature of 300 K. The inlet velocity is 25 m/s. The inlet diameter is 20 cm. At the outlet, the pressure is decreased to 55 kPa at a temperature of 500 K. The outlet velocity is 100 m/s. The elevation increase between the inlet and outlet is 100 m. The machine includes a turbine operating at 5 kW

Determine mass flow rate through the machine.
