Paul and Juston are carrying a sack or rice weighing 6.02x10^2 N on a pole between them. If the pole is 2.0 m long and the load is .50m away from Juston,what force should each boy exert to make it equilibrium. Neclect the weight of the pole.
F1 + F2 = 602 N.
F1 = (1.5/0.5)F2 = 3F2.
3F2 + F2 = 602.
F2 = 150.5 N. = Paul's force.
3F2 = 3 * 150.5 = 451.5 N. = Justin's
force.
Well, if Paul and Juston want to achieve equilibrium, they better not tip the scales! *ba dum tss*
Let's analyze the situation. The weight of the rice sack is acting downwards and can be represented by a force of 6.02x10^2 N. Since the pole is 2.0 m long, the weight of the rice is acting 0.50 m away from Juston.
To achieve equilibrium, the upward force applied by Paul and Juston should be equal to the downward force of the rice sack. Since there are two boys, they need to share the load. So each of them would exert half the force.
Therefore, each boy should exert a force of (6.02x10^2 N) / 2 = 3.01x10^2 N to keep things balanced. That way, they won't be in a bit of a pickle!
To solve this problem, we need to set up an equation by considering the forces acting on the pole.
Let's denote the force that Paul exerts as Fp and the force that Juston exerts as Fj.
First, we can calculate the torque caused by the sack of rice using the formula:
Torque = Force x Distance
The torque caused by the sack of rice is equal to the torque caused by the forces exerted by Paul and Juston on the pole. The torque caused by the sack of rice is given by:
Torque_sack = 6.02 x 10^2 N x 0.50 m
Next, let's calculate the torque exerted by Paul's force. Since the sack of rice is 0.50 m away from Juston and 1.50 m away from Paul (assuming the pole is in the middle), the torque exerted by Paul's force is given by:
Torque_Paul = Fp x 1.50 m
Finally, let's calculate the torque exerted by Juston's force. Since the sack of rice is 0.50 m away from Juston, the torque exerted by Juston's force is given by:
Torque_Juston = Fj x 0.50 m
According to the condition of equilibrium, the sum of the torques must be equal to zero:
Torque_sack + Torque_Paul + Torque_Juston = 0
Substituting the previously calculated values into the equation, we get:
6.02 x 10^2 N x 0.50 m + Fp x 1.50 m + Fj x 0.50 m = 0
Simplifying the equation, we have:
301 N + 1.5Fp + 0.5Fj = 0
Since the pole is in equilibrium, the forces exerted by Paul and Juston must cancel each other out. Thus, Fp = -Fj.
Substituting this relationship into the equation, we get:
301 N + 1.5Fp + 0.5(-Fp) = 0
301 N + 1.5Fp - 0.5Fp = 0
Combining like terms, we have:
301 N + Fp = 0
Finally, solving for Fp:
Fp = -301 N
Since Fp = -Fj, we have:
Fj = 301 N
Therefore, to make the pole in equilibrium, Paul should exert a force of 301 N, and Juston should also exert a force of 301 N in the opposite direction.
To find the force that each boy should exert to balance the sack of rice, we can set up an equilibrium equation. In this situation, the total torque acting on the pole must be zero.
Torque is the product of force and the perpendicular distance from the force to the axis of rotation. In this case, the axis of rotation is the point where the pole touches the ground.
First, let's find the torque exerted by the sack of rice. The weight of the sack (6.02x10^2 N) can be considered as acting at its center of mass, which is 0.50 m away from Juston.
The torque exerted by the sack of rice is given by:
Torque_sack = Force_sack * Distance_sack
Since the weight of the sack acts vertically downward, it creates a clockwise torque. So, we need to define the counterclockwise torque by the boys to balance it.
Now, let's find the torque exerted by Paul. The force exerted by Paul can be considered as acting at a point 1.50 m away from Juston (2.0 m - 0.50 m).
The torque exerted by Paul is given by:
Torque_Paul = Force_Paul * Distance_Paul
Next, let's find the torque exerted by Juston. Since the force exerted by Juston is acting at the same point as the sack (0.50 m away from him), the torque exerted by Juston will be zero.
Now, we can set up the equilibrium equation:
Torque_sack + Torque_Paul = 0
(Force_sack * Distance_sack) + (Force_Paul * Distance_Paul) = 0
Substituting the given values:
(6.02x10^2 N * 0.50 m) + (Force_Paul * 1.50 m) = 0
301 N + (Force_Paul * 1.50 m) = 0
Force_Paul = -301 N / 1.50 m
Force_Paul = -200 N
The negative sign indicates that the force exerted by Paul is in the opposite direction to the force exerted by the sack. Therefore, Paul should exert a force of 200 N in the opposite direction to the force exerted by the sack.
To find the force exerted by Juston, we can use the principle of equilibrium:
Force_Juston = Force_sack + Force_Paul
Force_Juston = 6.02x10^2 N + 200 N
Force_Juston = 802 N
Therefore, Juston should exert a force of 802 N towards the sack of rice.
