Here are the solutions to the lever problems: 2.4.4 Step 1: Identify the given values and rearrange the formula to find the effort arm. The load arm is 0.8 meters. The mechanical advantage (MA) is 6. From the formula MA = Effort armLoad arm, we can rearrange to find the effort arm: Effort arm = MA × Load arm Step 2: Substitute the values into the rearranged formula and calculate. Effort arm = 6 × 0.8\, m Effort arm = 4.8\, m The length of the effort arm is 4.8 meters. 2.4.5 Step 1: Identify the given values and rearrange the formula to find the load arm. The effort arm is 0.4 meters. The mechanical advantage (MA) is 0.5. From the formula MA = Effort armLoad arm, we can rearrange to find the load arm: Load arm = Effort armMA Step 2: Substitute the values into the rearranged formula and calculate. Load arm = 0.4\, m0.5 Load arm = 0.8\, m The length of the load arm is 0.8 meters. 2.4.7 Step 1: Identify the given values and rearrange the formula to find the effort arm. The load arm is 0.75 meters. The mechanical advantage (MA) is 0.33. From the formula MA = Effort armLoad arm, we can rearrange to find the effort arm: Effort arm = MA × Load arm Step 2: Substitute the values into the rearranged formula and calculate. Effort arm = 0.33 × 0.75\, m Effort arm = 0.2475\, m The length of the effort arm is 0.2475 meters. 2.5.1 Step 1: Identify the given values and the formula for mechanical advantage. The input arm (effort arm) is 3 meters. The output arm (load arm) is 0.75 meters. The formula for mechanical advantage (MA) is: MA = Input armOutput arm Step 2: Substitute the values into the formula and calculate. MA = 3\, m0.75\, m MA = 4 The mechanical advantage of the lever is 4. That's 2 down. 3 left today — send the next one.
