PHYSICS

Two forces of magnitude 10 N and 8 N are acting at a point. If the angle between the two forces is 60deg, determine the magnitude of the resultant force

• 15.62 N

• 18.32 N

• 20 N

• 11.25 N

What do you call the work done on a unit volume of material as the force is gradually increased from O to P, in N-m / m³

• Modulus of Resilience

• Young's Modulus

• Bulk Modulus

• Modulus of Toughness

These are forces which intersect a common point,

• Coplanar

• Collinear

• Concurrent

• Parallel

A simply supported beam of span 9m carries a uniformly varying load from zero at end A to 900 N/m at end B. Calculate the reactions at the two ends of the support

• 1350 N and 2700 N

• 1300 N and 2750 N

• 1200 N and 2600 N

• 1000 N and 2000 N

• 

Which of the following is the strength of the material at rupture

• Tensile Strength

• Breaking Strength

• Resillience

• Toughness

These are forces which are having common lines of action

• Coplanar

• Collinear

• Concurrent

• Parallel

• Elastic Range

• Plastic Range

• Yield Point

• Rupture

It is the point at which the material will have an appreciable elongation or yielding without any increase in the load

• Elastic Range

• Plastic Range

• Yield Point

• Rupture

If two forces, acting at a point be represented in magnitude and direction by two adjacent sides of a parallelogram, then their resultant is represented in magnitude and direction by the diagonal of the parallelogram passing through the point

• Lami's Theorem

• Law of Triangle Forces

• Law of Equilibrium

• Law of Parallelogram Forces

It is the ability of a material to absorb energy without creating a permanent distortion

• Resilience

• Toughness

• Tensile Strength

• Breaking Strength
