Question

Calculate the torque if a force of 30 Newton acts on a steering wheel at a distance of 4 m:

1) 60 Nm
2) 80 Nm
3) 120 Nm
4) 100 Nm​

Answer 1

Provided that:

• Force = 30 Newton
• Distance = 4 metres

To calculate:

• Torque

Solution:

• Torque = 120 Nm

Using concept:

• Torque formula

Using formula:

• τ = F × ⊥s

Where, τ denotes torque / moment of force, F denotes force and ⊥s denotes perpendicular distance.

Required solution:

↦ τ = F × ⊥s

↦ τ = 30 N × 4 m

↦ τ = 120 Nm

↦ Moment of force = 120 Nm

↦ Torque = 120 Nm

• Therefore, option (3) is correct! $\:$

Answer 2

⟼ Given :-

• Force = 30 Newton
• Distance = 4 Metre

⠀⠀⠀⠀

⟼ To Find :-

• Torque of the steering wheel ?

⠀⠀⠀⠀

⟼ Answer :-

⠀⠀⠀⠀

⠀⠀⠀$\small\sf \pink{Torque \: Formula } : \: \small \bf{τ = F × ⊥s} \\ \\ \sf \pink{τ} = \small{30 \: N\times 4 \: M} \\ \\ \Longrightarrow\:\sf \pink{τ } = \small{120 \: NM}$

⠀⠀⠀⠀

⟼ Hence :-

• 3 option is correct .
