The figure shows a wire cutter. Determine the cutting force on the wire at A when the 75-N forces are applied to the handgrips. (Hint: The horizontal components of pin forces at B and D are zero due to symmetry.)

Version: b Determine the length b of the triangular load and its position a on the beam such that the equivalent resultant force is zero and the resultant couple moment is MR Let M₂ = -30 kN - m R Assume the intensities of the distributed loading be w = 12 kN/m w = 5 kN/m r Let the length of the beam be d = 8 m A b W₁ Wr d Note that the sign of MR indicates whether the couple moment is positive (CCW) or negative (CW). Also, position a may be negative, which indicates that the length of the rectangular load is shorter than the triangular load.

Problem Statement Based on Problem 4-59 from the textbook. The board is used to hold the end of the cross lug wrench in the position shown. If a torque of 30 N*m about x axis is required to tighten the nut, determine the required magnitude of the force F needed to turn the wrench. Force F lies in a verticla plane. = 280 mm b=235 mm -Fach Student: b Z 60° a - y
