a) (5 pts) Reproduce this sketch and show all relevant forces acting on the beam. (You may simplify the drawing of the man a stick figure will do, or a box.) b) [12 pts) Write the three equilibrium equations clearly (no numbers). c) (4 pts) Use these numbers to find the tension in the rope. Enter that in the moodle blank. Numbers: m = 89 kg, L = 6.6 m, m2 = 72.4 kg, d = 2.2 m, 0=39º. Answer:...
A uniform beam (mass M = 64.0 kg and length L = 4.90 m) is supported by two triangular supports that are placed a distance D = 2.94 m apart, as shown below. The left-most support is at the very end of the beam. A person (mass m = 22.0 kg) starts walking at constant speed v along the beam, beginning from some point between the two supports. How close can the person get to the right-most end of the...
Salim stands on a uniform beam of mass 90 kg that is resting on two supports, as shown in the diagram. He starts to walk slowly towards the right end of the beam. If Salim has a mass of 75 kg, how close will he be to the right end of the beam when its starts to tip over, in units of meters? 1.8 m 2.0 m 1.8 m
A worker stands a distance d = 0.250 m from the left end of a beam as shown in the figure. The beam is supported by three ropes. Find the tension in each rope (in N). Assume the beam is uniform, with length L = 2.00 m and mass 34.0 kg, and the weight of the worker is 710 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)...
Consider a rigid steel beam of length L = 13.5 m and mass mb = 398 kg resting on two supports, one at each end. A worker of mass mw = 78 kg sits on the beam at a distance x from support A. Refer to the figure. 1) When the worker sits at a distance x = 1.5 m from support A, calculate the force, in newtons, that support B must exert on the beam in order for it...
As shown below, a beam of mass M = 34 kg and length L = 6.8 m is attached to a vertical wall by a hinge and to a horizontal ceiling by a cable. The angle between the beam and the wall is theta = 75 degree, the angle between the cable and the ceiling is phi = 58 degree, and the cable is attached to the beam at a point which is a distance s = 2.2 m from...
A uniform beam resting on two pivots has a length L=6.00m and mass M =88.9kg. One pivot supports the left end of the beam and the second pivot is placed at distance ℓ=4.00m away from it. A woman of mass m=57.3KG steps onto the left end of the beam and begins walking to the right as in the figure below. Find the position x of the woman when the beam is about to tip. Define the origin (x=0) as the...
apt 12) Consider a construction worker of mass -78.5 kg standing at the end of a steel beam of length10.0 m and mass M-715 kg that is attached to the side of a building. A rope is attached midway along the beam making an angle 0-23.8 with the horizon and attached to the side of the building as shown in the figure below. rope pivot point (a) (6 pts) Draw and label the force vectors on the beam excluding forces...
please help for a-d. 1. Consider a beam of length L that is hinged at one end and supported by a cord at the other as shown in the figure. Suppose a mass M is hung at a distance of d from the hinge and that the supporting cord makes an angle of q 30 with the horizontal. Attached to the other end of the cord is a mass m. Take the mass of the beam m, to be equal...
(14%) Problem 7: Consider a rigid steel beam of length L - 15 m and mass m-419 kg resting on two supports, one at each end. A worker of mass m. = 71 kg sits on the beam at a distance x from support A. Refer to the figure. L ands 33% Part (a) Enter an expression for the force support B must exert on the beam in order for it to remain at rest, in terms of defined quantitie...
