Solving for Work: Tips and Hints | Work Equation Explained

AI Thread Summary
The discussion centers on solving a work-related problem where the equation W=F*d is presented, but the distance is unknown. A participant suggests integrating the force equation with respect to time to find the solution. They also mention that force can be derived from F=ma, allowing for the calculation of distance by dividing force by mass and integrating acceleration. The conversation emphasizes the need for a methodical approach to relate force, mass, and distance in the context of work. Overall, the thread provides insights on tackling physics problems involving work and force.

Hi, I am new to this forum and to any forums in general. I am not too sure as to how to solve this problem given the shown statements. I know the equation for work is W=F*d but I am not given any distance. The only thing I can think of is to integrate the Force equation with respect to time and plug in my t=5,0 but that won't give me the work. I don't think I can relate this to energy. Can someone give me a hint as to how to solve this problem?

U can find the force by the equation in terms of 5 sec interval. At the same time, u know that F = ma. Therefore, u can find distance d by dividing F by mass and integrate a twice.

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
