I need to consider fatigue failure for a E$7010$ electrode under a load of $0-5$kip. What is $k_a?(5$ pts$)$

a$.$ Not enough information to calculate

b$.0\mathrm{.}582$

c$.681$

d$.0\mathrm{.}934$

e$.1\mathrm{.}00$

A welded region has an area of $5m^2$ is undergoing fully reversible forces of $5$ N $.$ Wha is its ${}_a(pts)$

a$.5$ Pa

b$.0$ Pa

c$.2\mathrm{.}5$ Pa

d$.1$ Pa

f$.$ Not enough information to calculate
