Question

In the figure, forces A B C and D each have magnitude 50.0 N and act at the same point on the object.

SInce i can't copy paste the figure i will describe it.
there is a point P
forces A B C and D all share the same vertex
there is a distance of 20 cm between point P and the vertex of A B C and D
forces A and B form an angle of 60 degrees
Forces B and C form an angle of 30 degrees
Forces C and D form an angle of 60 Degrees

a)What torque (magnitude and direction) does A force exert on the object about point ?
b)What torque (magnitude and direction) does B force exert on the object about point ?
c)What torque (magnitude and direction) does C force exert on the object about point ?
d)What torque (magnitude and direction) does D force exert on the object about point ?
e)What is the total torque about point P ?

Explanation / Answer

there is a point P
forces A B C and D all share the same vertex
there is a distance of 20 cm between point P and the vertex of A B C and D
forces A and B form an angle of 60 degrees
Forces B and C form an angle of 30 degrees
Forces C and D form an angle of 60 Degrees

u didnot mention the angle that any vector makes with the horizontal.

i am assuming A is horizontal (in the same line of AP)

hence, 

torque due to A is 50sin60 * 20cm = 53Nm = 8.66Nm

torque due to B is zero

torque due to C is 50sin30 * 20cm = 5Nm

torque due to B is 50sin90 * 20cm = 10Nm

therefore total torque is 23.66Nm
