Consider an athlete wearing a weight boot, and from a sitting position, doing lower leg flexion/extension exercises to strengthen quadriceps muscles. The weight of the athlete's lower leg is W1 = 50 N and the weight of the boot is W2 = 100 N. As measured from the knee joint at point O, the center of gravity (point A) of the lower leg is located at a distance a = 20 cm and the center of gravity (point B) of the weight boot is located at a distance b = 50 cm. Determine the net moment generated about the knee joint when the lower leg is extended horizontally (position 1), and when the lower leg makes an angle of 25 deg (position 2), 55 deg (position 3), and 90 deg (position 4) with the horizontal.

Consider an athlete wearing a weight boot, and from a sitting position, doing lower leg flexion/extension exercises to
strengthen quadriceps muscles. The weight of the athlete's lower leg is W1 = 50 N and the weight of the boot is W2 =
100 N. As measured from the knee joint at point O, the center of gravity (point A) of the lower leg is located at a
distance a = 20 cm and the center of gravity (point B) of the weight boot is located at a distance b = 50 cm. Determine
the net moment generated about the knee joint when the lower leg is extended horizontally (position 1), and when the
lower leg makes an angle of 25 deg (position 2), 55 deg (position 3), and 90 deg (position 4) with the horizontal.

PROBLEM 1 For the engineering activity, current practical capacity is defined by the following requirements: 6,000 engineering hours for each product group that has been on the market or in development for 5 years or less, and 2,400 hours per product group of more than 5 years. Four product groups have less than 5 years' experience, and 10 product groups have more. There are 24 engineers, each paid a salary of P60,000. Each engineer can provide 2,000 hours of service per year. The actual engineering usage was 46,000 hours. The standard is 58% of current practical activity capacity. Case 1: Calculate the (1) activity volume and (2) unused capacity variances for the engineering activity Case 2: Suppose the operational managers have selected some improvement measures that promise to reduce non-value-added activity usage by 40% in the following year. Using the targeted reduction, establish kaizen standards for engineering, expressed both in physical and financial measures
