A riveted bracket is subjected to a load $P$ acting at an angle of theta from the vertical.

Give solution for the following:

Max. shear stress if $P=40kN,$ theta $=45$deg,

$b=100$mma$=150mm$ and $e=250mm$ in MPa.

$($answer: $82\mathrm{.}9$MPa $)$

Maximum value of $P$ if $e=250mm$ and the

allowable shearing stress is $120$MPa.

$($answer: $57\mathrm{.}8kN)$

Minimum eccentricity $"e"$ when $P=40kN$ if the

allowable shearing stress is $120$MPa.

$($answer: $442\mathrm{.}6)$

Refer to the figure, answers provided. Need solution.
