The best answer is D.
Stress is a force that acts on rock to change its shape or volume. Because stress is a force, it adds energy to the rock, which is stored in the rock until either the rock breaks or changes shape.
There are three kinds of stress, namely shearing, tension and compression.
Shearing- force that pushes a mass of rock in two opposite directions and can cause rock to break and slip apart or change shape.
Tension - force that pulls on the crust, stretching rock so that it becomes thinner in the middle.
Compression - force that squeezes rock until it folds or breaks
Answer:
The total normal force acting on the system is approximately 58.8 N
Explanation:
The masses arranged in the stack are;
3 kg, 2 kg, and 1 kg
The mass of the stack system, m = 3 kg + 2 kg + 1 kg = 6 kg
Weight = The force of gravity on an object = m·g
Where;
m = The mass of the object
g = The acceleration due to gravity ≈ 9.8 m/s²
∴ The weight of the stack system, W ≈ 6 kg × 9.8 m/s² ≈ 58.8 N
The direction of the weight force = Perpendicular to the surface (acting downwards)
From Newton's third law of motion, the normal force acts perpendicular to the plane and it is equal in magnitude to the force acting perpendicular to the plane
∴ The magnitude of the total normal force acting on the system = The magnitude of the weight of the system ≈ 58.8 N
The (magnitude of the) total normal force acting on the system ≈ 58.8 N
Answer:
15.64 KN
Explanation:
Given
Mass of the elevator = 1.70 × 10³ kg = 1700 kg
acceleration of the elevator = - 0.6 m/s²
Tension in the cable = ?
The free body diagram is given in the attached image
The net force acting on a body accelerates the body in the same direction as that in which the resultant is applied.
Force balance,
ma = T - mg
1700 (-0.6) = T - (1700×9.8)
T = 16660 - 1020 = 15640 N = 15.64 KN
