Sir Lancelot rides slowly out of the castle at Camelot and onto the 12.0-m-long drawbridge that passes over the moat (Figure 1). Unbeknownst to him, his enemies have partially severed the vertical cable holding up the front end of the bridge so that it will break under a tension of 5.80 x 10 N. The bridge has mass 200 kg and its center of gravity is at its center. Lancelot, his lance, his armor, and his horse together have a combined mass of 600 kg.

Concept explainers

Center of Gravity of a system

The centre of gravity is a property that is based on the geometry of a rigid body or any particle. It is described as an equilibrium point or a hypothetical location where the total weight of the body is concentrated.

Sir Lancelot rides slowly out of the castle at Camelot and
onto the 12.0-m-long drawbridge that passes over the moat
(Figure 1). Unbeknownst to him, his enemies have partially
severed the vertical cable holding up the front end of the
bridge so that it will break under a tension of 5.80 x 103 N.
The bridge has mass 200 kg and its center of gravity is at its
center. Lancelot, his lance, his armor, and his horse together
have a combined mass of 600 kg.
Part A
Will the cable break before Lancelot reaches the end of the drawbridge?
O yes
O no
Part B

When you bend over, a series of large muscles, the erector spinae, pull on your spine to hold you up. Figure shows a simplified model of the spine as a rod of length L that pivots at its lower end. In this model, the center of gravity of the 320 N weight of the upper torso is at the center of the spine. The 160 N weight of the head and arms acts at the top of the spine. The erector spinae muscles are modeled as a single muscle that acts at an 12° angle to the spine. Suppose the person shown bends over to an angle of 30° from the horizontal. a. What is the tension in the erector muscle? Hint: Align your x-axis with the axis of the spine.b. A force from the pelvic girdle acts on the base of the spine. What is the component of this force in the direction of the spine? (This large force is the cause of many back injuries).
Two people carry a heavy electric motor by placing it on a light board 2.10 mm long. One person lifts at one end with a force of 450 NN, and the other lifts the opposite end with a force of 570 NN. What is the weight of the motor? Express your answer in newtons. Where along the board is its center of gravity located? Express your answer in meters. Suppose the board is not light but weighs 190 NN, with its center of gravity at its center, and the two people each exert the same forces as before. What is the weight of the motor in this case? Express your answer in newtons. Where is its center of gravity located? Express your answer in meters.
To get up on the roof, a person (mass 82.0 kg) places a 6.60 m aluminum ladder (mass 11.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2 m from the bottom. The person is standing 3 m from the bottom. What are the magnitudes (in N) of the forces on the ladder at the top and bottom? top N bottom N
The experiment you did in lab is repeated, using a uniform metal bar that is 80.0 cm long instead of the meterstick. Since the bar is uniform, its center of gravity is at its center. The new experiment uses different hooks for hanging the masses from the bar, with mhook 5.0 g. As in the experiment you did in lab, X1 = 5.00 cm, m1 300.0 g, and Xp = 25.0 cm. In the 1 new experiment, you make the same measurements as in your lab and plot x versus The line that is the best fit to your data has slope 3800 cm · g. What is the mass of m2 + mhook the bar?
