SUMMARY

The torque equation for calculating torque with angles is defined as T = r(fsinθ). In this context, the torque (T) is derived from the radius (r), the force (f), and the sine of the angle (θ) between the force vector and the radius vector. The discussion clarifies that the sine function is essential in the torque calculation, as it relates to the vector cross product, which cannot be substituted with cosine in this scenario.

PREREQUISITES
  • Understanding of torque and its physical significance
  • Familiarity with vector mathematics and cross products
  • Knowledge of trigonometric functions, specifically sine and cosine
  • Basic principles of mechanics involving forces and angles
NEXT STEPS
  • Study the vector definition of torque and its applications in physics
  • Learn about the properties of vector cross products and their significance
  • Explore scenarios where torque is applied in real-world mechanics
  • Review trigonometric identities and their use in physics problems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and torque calculations, as well as educators seeking to clarify concepts related to vector mathematics and trigonometry.

I'm confused to whether or not there is ever any cases in which cos is substituted for sin?

Why do you say that? Do you know the vector definition of torque? The torque is the radius vector crossed with the force vector, and the vector cross product involves the sin() function.
