Sure! Here is a step-by-step guide to drawing a labeled free body diagram of the forces acting on the wheelbarrow:
Step 1: Start by drawing a rough sketch of the wheelbarrow. It can be a rectangular shape with handles.
Step 2: Label the wheelbarrow with the mass of the wheelbarrow and its contents. In this case, the total mass is given as 30 kg. Write "30 kg" on the wheelbarrow.
Step 3: Identify the force of gravity acting on the wheelbarrow. This force is always directed downward towards the ground. Draw an arrow pointing downward from the center of mass of the wheelbarrow and label it as "weight" or "W" with the unit of force (Newton, N) beside it.
Step 4: Since John is pushing the wheelbarrow, there is a force applied by John in the forward direction. Draw an arrow pointing horizontally to the right, starting from the point where John is pushing, and label it as "force applied" or "F" with the unit of force (N) beside it.
Step 5: Identify the force of friction acting on the wheelbarrow. Friction opposes the motion and is directed opposite to the applied force. Draw an arrow pointing horizontally to the left, opposite to the direction of the force applied by John, and label it as "friction" or "Ffr" with the unit of force (N) beside it.
Step 6: There might be other forces acting on the wheelbarrow, such as air resistance, but they are typically negligible compared to the main forces mentioned above. However, if there is any other force you want to include, identify it and draw it accordingly.
Step 7: Double-check your diagram to ensure all forces are labeled correctly.
And there you have it! A labeled free body diagram of the forces acting on the wheelbarrow filled with sand.
To draw a labeled free body diagram of all the forces acting on the wheelbarrow, we need to identify the different forces involved. Here are the forces acting on the wheelbarrow:
1. Weight (W): This force is due to the gravitational pull on the mass of the wheelbarrow and its contents. The weight acts vertically downwards, toward the center of the Earth. Its magnitude can be calculated using the formula W = m * g, where m is the mass and g is the acceleration due to gravity (approximately 9.8 m/s²).
2. Normal Force (N): This force is exerted by the ground on the wheelbarrow perpendicular to the surface of contact. It counteracts the weight and prevents the wheelbarrow from sinking into the ground. The magnitude of the normal force is equal to the weight when the wheelbarrow is at rest on a level surface.
3. Force of Tension (T): As John pushes the wheelbarrow forward, he applies a force on the handle. This force, known as the force of tension, is directed along the handle and acts to move the wheelbarrow. It is transmitted to the wheelbarrow through the connection between the handle and the wheelbarrow itself.
Therefore, the labeled free body diagram of the forces acting on the wheelbarrow will include:
1. A downward arrow labeled "W" to represent the weight.
2. An upward arrow labeled "N" to represent the normal force.
3. A forward arrow labeled "T" to represent the force of tension.
Please note that the magnitude of the forces may vary depending on the specific situation, but their direction and relative labels will remain the same.
