i have drawn FBD and labbelled all of the forces and tried to solve for alpha using simultaneous equations and other methods (the names of which im not too sure). could anyone please tell me what to do next?

much obliged

50-F-1250sinaplha=0

f=ma perpendicular to slope

N-1250cosalpha=0

F=mu*N

mu=0.1

N=F/mu;N=10F

; 10F-1250cosalpha=0

F+1250sinalpha=50

ps, im half asleep so excuse any blatant stupidity
