A forklift operator has lifted a crate $($ mass $=m_1),$ and has stopped on a sloped ramp $($angle $=a).$ The forklift itself $($mass $=m_2),$ has a centre of mass

acting at point $G.$ The rear wheel acts as a roller support at point $B$ whereas there are brakes on the front wheels at point $A($pin support$).$

Given the information in the table above, determine:

the reactions at the rear wheel, point $B,$

$kN,(3$ sigfig$)$

the reactions at the front wheel, point $A,$

$F_y=$

$kN,(3$ sigfig$)$

$F_x=$

$kN,(3$ sigfig$)$

the maximum height the forklift can lift up to without tipping over $($at the same place and with the same mass$),$

$[$m$],(3$ sigfig$)$
