You’re a highway safety engineer, and you’re asked to specify bolt sizes so the traffic signal shown in the Figure below won’t fall over. The figure indicates the masses and positions of the structure’s various parts. The structure is mounted with two bolts, located symmetrically about the vertical member’s centerline, as shown. What tension force must the left-hand bolt be capable of withst

The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb.    Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.

What is the student’s weight?

Two children of mass 15 kg and 26 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw.If the children are separated by a distance of 3.0 m, at what distance, in meters, from the pivot point is the smaller child sitting in order to maintain the balance? r1 =

Bob and Anna sit on opposite ends of a uniform see-saw which is 12.0 m in length. The see-saw is balanced by a fulcrum which is located 4.00 m from Bob. Bob has a mass of 85.0 kg, and the see-saw itself has a mass of 100 kg. Anna’s mass is unknown. NOTE THAT THE FULCRUM IS NOT PLACED AT THE CENTER OF MASS OF THE SEE- SAW!!! a)   What is the net torque on the see-saw? Explain clearly and briefly how you know. b) Draw a properly labeled extended force diagram of the see-saw   c) Solve for Anna’s mass. Show your work clearly!

A 3.0-m -long ladder, as shown in (Figure 1), leans against a frictionless wall. The coefficient of static friction between the ladder and the floor is 0.50.

Three children are trying to balance on a seesaw.  The seesaw is 4.1 m long and pivots about a rock at its center.  Louie and Laura are already sitting on opposite ends.  If Martha weighs 33 kg, where should she sit so as to balance the seesaw?

A uniform 36.0-kg beam of length ℓ = 4.20 m is supported by a vertical rope located d = 1.20 m from its left end as in the figure below. The right end of the beam is supported by a vertical column. Answer parts a-b.

A painter stands on a uniform horizontal beam of length L = 6.0 m that is held in equilibrium by support cables attached to the roof as shown in Figure 3. The beam has a weight Wb = 250.0 N and the tensions on the left and the right ends are measured to be Tl = 360.0 N and Tl = 200.0 N respectively. A. Calculate the weight of the painter Wp , and Wb. the distance x where the painter is standing.
