Homework Help Overview

The discussion revolves around a static slope problem involving a block positioned at a distance from an incline, connected by a cable to a fulcrum. Participants are exploring the forces acting on the system, particularly the downward force at the fulcrum due to the block's weight and the angle of the incline.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the calculation of the force in the cable, with one suggesting it can be expressed as m*g*sin(theta). There are inquiries about the components of this force and how they relate to the overall system.

Discussion Status

The discussion is ongoing, with participants sharing their thoughts on the force calculation and seeking clarification on the components involved. Visual aids have been introduced to enhance understanding, indicating an active exploration of the problem.

Contextual Notes

There may be assumptions about the setup and the angle of the incline that are not fully articulated, as well as potential missing information regarding the mass and distance involved in the problem.

Homework Statement


If i have a block that is d distance back from a slope, and I have cable coming out of the block (lets assume at ground level) that goes over to a fulcrum at the ledge of an incline of angle theta down to a block of mass m. What is the downward force at the fulcrum point?
2. Attempt at a solution

I can find the force of the string as m*g*sin(theta)
