Here are the calculations for the forces related to the shaping machine ram: Given: Mass of the ram, m = 200 kg Coefficient of friction, = 0.07 Acceleration due to gravity, g = 9.81 m/s^2 (standard value) 1.1 The horizontal force required to move the ram. Step 1: Calculate the normal force (N). The normal force is equal to the weight of the ram, as it's moving horizontally. N = mg N = (200 kg) (9.81 m/s^2) N = 1962 N Step 2: Calculate the horizontal force (F_h). The horizontal force required to move the ram is equal to the force of friction (F_f). F_h = F_f = N F_h = (0.07) (1962 N) F_h = 137.34 N The horizontal force required to move the ram is: 137.34 N 1.2 The coefficient of friction if the force to move the ram is increased by 30%. Step 1: Calculate the new horizontal force (F_h, new). The force is increased by 30% from the original force calculated in 1.1. F_h, new = F_h + (0.30 × F_h) F_h, new = 137.34 N + (0.30 × 137.34 N) F_h, new = 137.34 N + 41.202 N F_h, new = 178.542 N Step 2: Calculate the new coefficient of friction (_new). The normal force (N) remains the same. F_h, new = _new N Rearrange to solve for _new: _new = F_h, newN _new = 178.542 N1962 N _new ≈ 0.0910 The new coefficient of friction is: 0.091 What's next?
