roblem 4.59 ) 110120 (> The board is used to hold the end of a tour-way lug wrench in position Figure 1) Part A lfatorque of 41N-En about the Z axis is required to 5ghten the nut, determine the required magnitude ofthfoeceF that the man's foot must apply on the end of the wrench in order to turn it. Force F les in a vertical plane Express your answer to three significant figures and include the appropriate units. igure . Value Units Submit Request Answer -250 mm Provide Feedback Next > 250 mm

Explanation / Answer

from the diagram we can see
the moment M is equal to
M = F*sin(60)*250 mm
F is applied force
hence
M = F*sin(60)*250/1000
F = 1000M/250*sin(60)
M = 41 Nm
hence
F = 189.37 N
