<span>Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, the rate of change (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis.</span>

A bicycle pedal is pushed straight downwards by a foot with a 11 Newton force. The shaft of the pedal is 20 cm long. If the shaf
galben [10]

Answer: 1.1 Nm

Step-by-step explanation:

The formula for torque is T = r · F · sin θ

where θ = π/6, r = 20 cm = 0.2 m, F = 11 N

formula for converting radians to degrees is 1 rad × 180/π = 57.296°

θ = π/6 · 180/π = 30°

Substituting r into the formula for torque, we have

T = 0.2 x 11 x sin 30° = 0.2 x 11 x 0.5

T = 1.1 Nm
