Answer:
9.375Nm
Explanation:
The formula for calculating torque τ = Frsin∅ where;
F = applied force (in newton)
r = radius (in metres)
∅ = angle that the force made with the bar.
Given F= 25N, r = 0.75m and ∅ = 30°
torque on the bar τ = 25*0.75*sin30°
τ = 25*0.75*0.5
τ = 9.375Nm
The torque on the bar is 9.375Nm
The torque on the bar is - 9.375 N
From the information given:
- The force applied to the bar = 25N
- the distance (d) of the force from the end = 0.75 m
- the angle of θ = 30°
The diagrammatic expression of the question given can be seen in the image attached below, from the image the direction of the torque on the bar is in a clockwise direction as such, we will take the negative sign into consideration.
∴
The torque can be computed by using the formula:
T = - (F × d × sin θ)
T = - (25 N × 0.75 m × sin 30)
T = - (25 N × 0.75 m × 0.5)
T = -9.375 N
