Question

A dynamic compression force, F = 5 + 2 cos(5t) kN, is applied to the rod of a cylinder with a cap-side area of 8 x 10^{-3}10 −3 m^2 2 and a force efficiency of 90%. The cylinder moves at a constant velocity of 1 cm/s. If the rod-side of the cylinder is atmospheric, what is the gauge pressure in the cap-side of the actuator at time t = 4?

Answer 1

Answer:

verify whether the value of x given in each case are the zeroes of polynomial or not

1.p(x)=2x+1;x=-1/2

2.p(x)=5x- pie ;x=-3/2

3.p(x)=xsq -1;x=+1

4.p(x)=(x-1)(x+2);x=-1,-2

5. p(y)=ysq ;y=0

6.p(x)ax+b;x=-b/a

7.f(x)=3xsq-1;x=-1/root3 ,2/root3

8.f(x)=2x-1,x=1/2,-1/2
