Reaction forces Definition and 63 Threads

A 3 pin frame ABCDE is supported at A and E. it supports vertical loads of 60 kN at B 80 kN at c and 100 kN at D as well as a horizontal UDL of 50kNm along DE. Calculate the reaction forces. I have REV = 124 kN and RAV = 116 kN. REH = 115.3kN and RAH = 215.3 kN. Are these correct Next...

Static Equilibrium... Please help Homework Statement The J-shaped member shown in the figure is supported by a cable DE and a single journal bearing with a square shaft at A. Determine the reaction forces and at support A required to keep the system in equilibrium. The cylinder has a weight =...

A linear actuator is wedged between two solid walls as shown in the diagram below. The linear actuator is pushing outwards with a force of 10N. What are the magnitudes of the forces labelled in the diagrams? I reckon that F1 = F2 = R1 = R2. However, I'm not sure if F1 = F2 = 5N or 10N...

Homework Statement The uniform horizontal beam is hinged to the ground at A and supported by a frictionless roller at D. Distance A to B is 4 m, A to D is 3 m. A force P with a magnitude of 1000N makes an angle 60 degrees with the horizontal at point B. The total Weight of beam is 400 N. By...

If I found myself floating in zero-G in a space station, with a propellant in my hand, is it possible to use the propellant to impart a spin without imparting any lateral movement? To myself up I'd hold the can at arm's length, and point it 90 degrees sideways (just like a maneuvering jet)...

Homework Statement Homework Equations M = F * D The Attempt at a Solution For a, I need to find the reaction force on the right side. So what I first did was make the sum of the moment on the left equals zero. 0 = M_0 + r_y * L. r_y = \frac{-M_0}{L} I think this is right...

Homework Statement An assembly is shown in Figure 1, GH, HK and HNL are three cables. The mass of box L is 350 kg, a) Determine the mass of box K in order to make angle teta = 30 degrees b) Determine the reaction forces at supports G and N. i started by converting...

I have a square thin plate 620mm*620mm that is simply supported on all four edges and is subjected to a uniformly distributed patch load (q0) over a central area of 58mm*58mm. I have calculated the central deflection to be (3.137x〖10〗^(-6) q0 (mm) via navier solution and the max stress in the...

Homework Statement Basically, I am looking to find the reaction forces at the pin joint on the right side of the structure. I just realized it is not labeled on my diagram, but it is the pin on the link opposite of E. Where the 13 degree angle is measured from. Homework Equations I have...

Hi, I was just wondering in what directions the reaction forces go in ball and socket joints? Are there reactions in the x, y, and z plane or just in 2 of those planes.

guys, how can u compute for the reaction forces of supports A & B w/ a 2 degree load...? a link is provided below thanks! http://img49.imageshack.us/img49/7876/19uh.jpg

Just checking these other problems 1)Bicycle has wheels with circumference of 2m. What is the linear speed of the bicycle when the wehels rotate at 1 rev/sec. 2m/s 2) A 10,000N vehicle is stalled 1/4 the way across a bridge. What are the two additional recation forces that are...

Im having a bit of trouble with this problem: A crane of mass 5288.51 kg supports a load of 789.67 kg. The crane are is 7m long and the angle it makes wiht the horizontal is 47.627 degrees. The distance between the front and rear wheels is 4 m. Assume that the center of mass of the...
