Torque is dependent on the angle between the force applied and the length of the level arm. when is the torque maximum? not enough information. î¸ = 90 î¸ = 0 î¸ = 45

90 degree

Explanation:

According to the formula of torque

torque = force x displacement x Sine of angle between force and displacement

So, for the maximum torque, the value of Sin theta should be maximum.

the maximum value of Sin theta is 1.

that means the value of theta is 90 degree.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
