Answer 2

❥Given:−

➬ Length of spanner = 30 cm

➬ Force applied = 45 N

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline\color{red}{⧪{\pmb{\sf{ \: To \: Find :-}}}}}$

➬ Moment force on the nut = ?

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\large\underline{\underline\color{green}{⧪{\pmb{\sf{ \: Solution :-}}}}}$

❒ We know that :

$\large\green\bigstar{\underline{\boxed{\sf{Moment \: of \: Force = Force \times Distance}}}}$

❒ Required converting :

1m = 100 cm .So,

$\blue{\leadsto}{\sf{30 cm = \cancel\dfrac{30}{100}}}$

▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃

❒ Now Moment of force :

$\large{:\longmapsto{\sf{Moment \: of \: force = Force \times Distance}}}$

$\large{:\longmapsto{\sf{ \: \: \: \: \: \: \: 45 \times 0.3}}}$

${\large\orange{:\longmapsto{\sf{ Moment \: of \: force = {\green{\underline{\sf{ 13.5 \: N}}}}}}}}$

❒ Therefore :

❝ Moment of force on the nut is 13.5 Nm.❞
