Answer 1

Answer:

mark me the brainliest

if u i will follow you

Explanation:

Depending on whether it is routed to the cap end or rod end, the pressurized fluid may extend or retract the cylinder, respectively. In either case, force generated by gravity or a spring returns the piston rod to its original state. ... Single-acting cylinders can be spring-extend or the more common spring-return type.

Answer 2

Answer:

S = \frac{1}-{2} [u+v]t

              v = u+at

Pl mark me brainliest

            v-u = at

                t = \frac{v-u}-{a}

                S = \frac{1}-{2} [u+v]t

                   = \frac{1}-{2} [u+v][\frac{u-v}-{a} ]

              as = \frac{1}-{2} [u+v][u-v]

            2as = [u+v][u-v]

                   = v^{2} - u^{2}
