Write a function "sumsteps2" that calculates and returns the sum of 1 to n in increments of 2, where n is an argument passed to the function. For example, if 11 is passed, it will return the sum of 1 + 3 + 5 + 7 + 9 + 11. Do this using a for loop. Calling the function will look like this: >> sumsteps2(11)ans =36

The poppet of the pressure relief valve must move 0.2 in from the fully closed position in order to pass the full pump flow at the prv setting (full pump flow pressure). the poppet has a 0.85 in3 area on which system pressure acts. assuming that the relief valve cracking pressure should be 15% higher than the pressure required to overcome the hydraulic cylinder punching operation, find the required a) spring constant of the compression spring in the prv, b) initial compression of the spring from its free-length condition as set by the spring-adjustment mechanism of the prv (poppet held against its seat by spring).
