SITUATION $1!$

A plate is connected to a column by bolts and

cames an eccentric load as shown in the figure.

The load $P=27\mathrm{.}5kN,$ eccentricity, $e=200mm.$

The dimension $a=b=150mm.$

Assume that the load $P$ acts through the

centroid of the bolls, which of the following most

nearly gives the stress on the bolts, in MPa $.$

a$.23\mathrm{.}5$

b$.21\mathrm{.}88$

c$.10\mathrm{.}94$

d$.25\mathrm{.}60$

Assume that the only load acting on the

connection is a moment equal to load $P$

muttiplied by its eccentricity, e$.$ Which of the

following most nearty gives the distance from

the centroid of the bolts in millimeters where a

bolt is placed so that the stress will be equal

and opposite to the stress in the first problem?

a$.56\mathrm{.}5$

b$.65\mathrm{.}1$

c$.60\mathrm{.}4$

d$.53\mathrm{.}2$

Which of the following most nearty gives the

eccentricity of the load $P$ measured from the

instantaneous center of the bolts?

a$.256\mathrm{.}5$ mm

b$.265\mathrm{.}1$ mm

c$.,260\mathrm{.}1mm$

d$.253\mathrm{.}2$ mm
