Homework Statement \int(2dx/(x^2+4) from x= -\infty to x=2 Homework Equations No specific ones. The Attempt at a Solution So, from there I tried to split the integral into two, integrating between 2 and -2, and -2 and -\infty, but I got very lost trying to take the limits for these, partly...

Ah. Well, that was pretty careless of me. Thanks for that. Okay, so... Tsin60(6 m) - (1000 N)(5 m) - (500 N)(9 m) = 0 T=1828.28 I take it I would be correct with using subtraction in that equation then? Rx - 1828.28cos60=0 Rx=914.14 N However, I still would like confirmation on which...

1. Homework Statement A 10 meter beam with a mass of 100 kg is hinged at the wall with a supporting cable at 6 meters from the hinge, making a 60 degree with the beam. There is a 50 kg person located at 9 meters from the hinge. Assuming equilibrium, what is the tension on the cable, the force...

Homework Statement A 15 meter beam jutting out of the side of a building is held by a hinge (at the wall) and a cable at 10 meters from the wall. The angle between the beam and the cable is 60 degrees and the mass of the beam is 250 kg. If a 1000 N object is located on the beam, 7 meters...

Thanks for the reply, the insight, and the welcome. So, if I'm understanding what you're saying, then #5 is simply asking me to find the Potential Energy that exists at Point A, without taking into account the remaining Potential Energy (albeit in a different direction) that will exist beyond...

Homework Statement This is a simple, yet rather convoluted problem, so please, bear with me. An 80 Kg man on a sled is being chased by a lion down a 60 meter slope (μk = .13) with an incline of 30°. At the end of the slope, there is a 100 meter cliff. Also, there is a 20-meter-long rope at...
