What else can I help you with?
A pendulum consists of an object of mass 1.21kg tht hangs at the end of a massless bar a distance 1.28m from the pivot point calculate the magnitude of the torque due to gravity about the pivot point?
The torque is the component of the weight that is perpendicular to the bar. So when the bar hangs vertically down, parallel to the force of gravity, there is no torque. If the bar makes an angle "A" with the vertical then the component of weight perpendicular to the bar would be mgSin(A) and the torque would be mgLSin(A) , where m= 1.21 kg, and L = 1.28m, g=9.8m/ss , so all you need is the angle "A".
Why does a bar magnet placed in S-N direction turn towards N-S direction when torque acting on it is zero?
If the bar magnet turned then there was a torque acting upon it. Torque is defined as a turning force or moment.

A horizontal bar is fixed to the wall at one of the ends What is the torque at the fixation point?
The reaction at the fixation point(let's mark it 'A' point) will consist of reaction force and reaction torque. The net force for static item, consisting of sum of all the forces and the net torque have both to equal zero. To calculate force and torque at the fixation point, we need to know two things: mass of the bar and horizontal displacement of bar's center of mass from the fixation point. Since there are no forces acting in the horizontal plane, we can only take z(height) axis into consideration for forces. Reaction plus force of gravity have to be zero: RA + Q = 0, where Q denotes weight and is equal to Q = m * g, where m is mass of the bar. Calculated, RA = -Q, which means that reaction force is equal to weight, but directed in opposite way. Sum of all the torques in the bar has to be zero: MA + Q * l = 0, where MA is reaction torque at the fixation point, Q as above and l is distance from fixation point to bar's center of mass. Calculated: MA = -Q * l
