i am stuck with a couple of problems to do with transfer functions.

For the above system i need to know what the overall transfer function is. I have had a go and got an answer of 0.99mm/V. I am not sure if this is correct or if the units of measurement are correct (mm per volt?)

My next problem i have no idea how to calculte this one

if anyone can help or is experienced in mechatronics i would be ever so greatful

thank you

andy
