there are two children playing on a playground seesaw. one child has a mass of 25 kg the child sits on one end of the long uniform beam which has a mass of 20 kg. and another 45 kg child sits on the other end., the seesaw balances when a fulcrum is placed below the beam a distance of 1.50 m from the 25 kg-child, how long is the beam?
A seesaw consisting of a uniform board of mass and length supports at rest a father and daughter with masses my and respectively, as shown in the figure. The support (called the futrum) is under the center of gravity of the board, the father is a distance from the center, and the daughter is a distance from the center A balanced system ME (a) Determine the magnitude of the upward forcen exerted by the support on the board SOLUTION Conceptualize...
Two children are sitting on opposite ends of a scesaw of negligible mass. If 40 kg child is 2.0 m from the pivoted point, how far from the pivot point will the other 30 kg child sit on the seesaw to be at equilibrium? (draw diagram to show vectors) A uniform 2000 kg beam 10 m long supports a 500 kg weight 3 meters from the right support. Calculate the forces on each of the vertical support columns? (draw diagram...
A 3-m-long rigid beam with a mass of 100 kg is supported at each
end. An 80-kg student stands 2.0 m away from support 1 as seen in
the figure
A) Write down Newton's second law for the beam.
B) Using support 1 as your center of rotation, write down the
torque equation of the beam.

A uniform plank that is 4.00 m long has a mass of 7.00 kg. The plank is supported by two sawhorses, one 3.56 m from the right end of the plank and the other 1.50 m from the right end of the plank. A cat of mass 2.63 kg is sitting on the plank at a distance of 1.75 m from the right end of the plank. (a) Draw a free body diagram showing the four forces acting ON the...
A seesaw has an irregularly distributed mass of 40 kg k g , a length of 3.0 m m , and a fulcrum beneath its midpoint. It is balanced when a 60-kg k g person sits on one end and a 80-kg k g person sits on the other end. 1. Express your answer with the appropriate units. Enter negative value if the center of mass is located closer to the 60-kgkg person and positive value if the center of...
Suppose two children are using a uniform seesaw that is 3.00 m long and has its center of mass over the pivot. The first child has a mass of 30.0 kg and sits 1.40 m from the pivot. (a) Calculate where the second 18.0 kg child must sit to balance the seesaw. (b) What is unreasonable about the result? (c) Which premise is unreasonable, or which premises are inconsistent? Please show work and explanations.
Two kids create a makeshift seesaw by setting a 4-m long uniform plank on a saw horse. The saw horse is 0.5 m to the left of the center of mass of the plank. The child of mass m1 = 48 kg sits at the left end of the plank. The child of mass m2 = 35 kg sits 1 m to the right of the center of mass of the plank. What is the mass of the plank?
II. Two children are sitting on a massless 4.0 m long seesaw which has a pivot at the middle point. If one child, with a mass of 36 kg sits 1.2 m from the pivot, where must the other child, of mass 54 kg, sit so that the seesaw remains in equilibrium? a. 0.6 m b. 0.8 m c. 1.2 m d. 1.4 m e. None of the above
A 32.0-kilogram child sits on a uniform seesaw of negligible mass; she is 2.10 m from the pivot point (or fulcrum). How far from the pivot point on the other side will her 22.0-kilogram playmate have to sit for the seesaw to be in equilibrium?
