How do you do part b?

ok i may know

there are 3 forces on the beam

the weight vertically downwards

tension at point d directed to point c

force exerted by the wall at point a

weight is represented with the vector W =mg where m is the mass and g is the accelereation

from gravity

and m =20 and g is 9.8 i belive unless its different from gcse

Tsin(30) = mg

T sin(30°) = (20 kg)(9.8 m/s^2)

the tension is pointed to c at an upwards angle og 30 from horixontal

Due to the force exerted by the wall at point A as the beam is in equilibrium the force exerted must balance the horizontal coomponents

thus the force must act left

<@&791435371564892232> i think thats right

[violet viper]

i think the answer was an angle rather than left or right

[worn thistle]

oh 😭

[violet viper]

ty anyways

[worn thistle]

np

[violet viper]

i think ur "idea" is right tho

[worn thistle]

ye

i dont know how to work out the angle
