A simply supported beam supports a single load at a single point along its length. What is the formula to calculate the support reaction at R1?
R1 = (F x L1) / (L1 + L2)
R1 = (F x L1) / (L2)
R1 = (F x L2) / (L1)
R1 = (F x L2) / (L1 + L2)
The energy possessed by a flywheel because of its rotary motion is an example of:
Braking force
Rotational kinetic energy
Gravity
Tractive effort
In which of the following force systems do all forces pass through a single point?
Concurrent
Kinetic
Non-concurrent
Coplanar
What is acceleration?
Change in the velocity of an object over time, measured in m/s²
Change in the velocity of an object over time, measured in m/s
The motion of an object that is moving very fast
Change in the position of an object over time, measured in m/s
Newton’s first law states … ?
Energy cannot be created or destroyed, just changed between different forms
An object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force
An object is in equilibrium if the forces acting on it are zero
The acceleration of an object produced by a force is proportional to the mass of the object in the direction opposite to the force
Which of the following statements is true for a simply supported beam with uniformly distributed loading?
The maximum value of the shear force is at the midpoint of the beam
The bending moment diagram will be a sloping straight line passing through the midpoint
The maximum value of the bending moment will be experienced at the two ends of the beam
The reaction forces at each end of the beam will be the same
