How can we calculate the kinetic energy of a system with two hinged sticks?

Click For Summary
SUMMARY

The discussion focuses on calculating the kinetic energy of a system consisting of two hinged sticks, both with equal mass and length. The left stick is fixed at one end to a wall, while the right end is hinged to the second stick. Key parameters for the calculation include mass (m), length (l), and the angle (ß) with the ground. The kinetic energy can be derived by considering gravitational forces, initial angles, and hinge friction, although specific values for these parameters were not provided in the discussion.

PREREQUISITES
  • Understanding of basic physics concepts, particularly kinetic energy.
  • Familiarity with angular motion and hinge mechanics.
  • Knowledge of gravitational forces and constants.
  • Ability to apply trigonometric functions to physical systems.
NEXT STEPS
  • Research the formula for kinetic energy in rotational systems.
  • Learn about the effects of hinge friction on mechanical systems.
  • Explore the role of gravitational constants in physics problems.
  • Study the principles of angular displacement and its impact on energy calculations.
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the dynamics of hinged systems and energy calculations.

we have 2 stickcs have same mass and length. the left stick's left point is hinged to wall and the right point of the stick is hinged the other stick. then we realese the system . when the sticks make the ß angle with the ground find the kinetic energy of system... solution must include m l and ß parameters...:rolleyes:http://imajr.com/fizik1_402477

According to the rules, you have to show, how much you know about the problem. Show some initial steps.
 
D'oh! And I am doing your homework why??

There are a couple of issues.

Why a wall?
What is the gravity constant in this scenario?
What is the friction of the hinge?
What is the initial angle B at which the mechanism is released?

Just a few initial questions.
